Serious crash rates are a hockey stick pattern. 20% of the drivers cause 80% of the crashes, to a rough approximation. For the worst 20% of drivers, the Waymo is almost certainly better already.

Honestly, at this point I am more interested in whether they can operate their service profitably and affordably, because they are clearly nailing the technical side.

For example data from a 100 driver study, see table 2.11, p. 29. https://rosap.ntl.bts.gov/view/dot/37370 Roughly the same number of drivers had 0 or 1 near-crashes as had 13-50+. One of the drivers had 56 near crashes and 4 actual crashes in less than 20K miles! So the average isn't that helpful here.

Terr_

Hmmm, perhaps a more-valuable representation would be how the average Waymo vehicle would place as a percentile ranking among human drivers, in accidents-per-mile.

Ex: "X% of humans do better than Waymo does in accidents per mile."

That would give us an intuition for what portion of humans ought to let the machine do the work.

P.S.: On the flip-side, it would not tell us how often those people drove. For example, if the Y% of worse-drivers happen to be people who barely ever drive in the first place, then helping automate that away wouldn't be as valuable. In contrast, if they were the ones who did the most driving...

chii

the nature of the accidents also makes a difference tho.

A small fender bender is common in human drivers. A catastrophic crash (like t-boning into a bus) is rare (it'd make the news for example).

Autodriving, on the other hand, almost never makes fender benders. But they do t-bone into busses in rare occasions - which also makes the news.

Terr_

If only it were easier to get the stats in the form of "damage in property/lives in the form of dollars per mile driven", that would let us kinda-combine both big tragic events with fender-benders.

(Yeah, I know it means putting an actuarial cost on a human life, but statistics means mathing things up.)

asielen

It may be more fair to compare them to Uber drivers and taxis and at least on that comparison haven't ridden in thousands of Uber and taxis and a couple dozen waymos, it is better than 100%.

Anecdotal of course but within my circle people are becoming Waymo first over other options almost entirely because of the better experience and perceived better driving. And parents in my circle also trust that a waymo won't mow them down in a crosswalk. Which is more than you can say for many drivers in SF.

seizethecheese

With a distribution like this, percentile would be misleading, though

conorjh

isnt it a bit odd they always seem to be at the scene of a crash but somehow always a victim?

I saw a transit enthusiast YouTube video try out Waymo from the most distant part of the network to fisherman’s wharf in SF and it cost twice as much as an Uber while having a longer wait time for a car.

It also couldn’t operate on the highway so the transit time was nearly double.

One shouldn’t underestimate how economical real human operators are. It’s not like Uber drivers make a ton of money. Uber drivers often have zero capital expense since they are driving vehicles they already own. Waymo can’t share the business expense of their vehicles with their employees and have them drive them home and to the grocery store.

I’m sure it’ll improve but this tells me that Waymo’s price per vehicle including all the R&D expenses must be astronomical. They are burning $2 billion a year at the current rate even though they have revenue service.

Plus, they actually have a lot of human operators to correct issues and talk to police and things like that. Last number I found on that was over one person per vehicle but I’m not sure if anyone knows for sure.

I saw a transit enthusiast YouTube video try out Waymo from the most distant part of the network to fisherman’s wharf in SF and it cost twice as much as an Uber, had a longer wait time for a car, and cost about double.

That's literally an edge case. For shorter trips, I've found it to be slightly cheaper (especially factoring in the lack of tips) with maybe a slightly longer wait.

nemothekid

I don't really find this to be the case at all. I've had Waymo for ~2 years now (since the private program), and I've never noticed it being quicker or cheaper than an Uber. I have several hundred rides; I prefer the service - but I've never once told people it's cheaper or faster.

Currently, on Wednesday March 26th at 8:34 a ride from Bar Part Time in the Mission to Verjus in North Beach is $21.17 with a estimated 8 minute pickup time. The same ride on UberX has an estimated 2 minute pickup time at a cost of $15.34. I could see it being cheaper if you top 20% - but I don't tip nearly that high on Uber rides.

I will admit that I could possibly be self-selecting to peak times as I own a car in the city, so I only use ride share in the evenings; so it may very well be the case that the price/wait is more competitive at off-peak hours.

Furthermore, it's quite surprising to me that it seems that the human labor cost doesn't affect the price at all. The only price controls seems to be demand and the latent demand is enough to create a price floor where there is always a human that is willing to drive. It also seems like plain old logistics and traffic will prevent Waymo from providing enough supply to offer dirt cheap rides. The fact that a ride that would have cost me $5 in 2016 is almost 4x as much with "magic self driving technology" is not something I could have told my 2016 self.

fallinghawks

I've taken Waymo only twice (I try to avoid SF), from the ferry building to Chinatown, then back. Both times it was more expensive than Lyft with tip, but only by $2-3. It's good to know it can be cheaper.

dangus

Still, it kind of sounded like any trip involving the highway would be advantage Uber.

fossuser

The wait times have gotten better, they're getting freeway approval shortly which will be nice, the price is still at a premium (but worth it imo). I only take Waymo in SF now.

The only time I take Uber in the bay area is to the airport (and when they approve Waymo for SFO I won't take Uber then either).

BurritoAlPastor

I generally find that Waymos are cheaper than Uber/Lyft including tip.

I’ve also seen that, although Uber and Lyft peak times seem correlated to each other, they seem uncorrelated to Waymo peak activity. But this might be stabilizing as Waymo ridership increases.

Mawr

Fascinatingly, every argument you make is wrong.

> it cost twice as much as an Uber

Surely incidental since the typical price per ride is about the same. Generally though, the relationship between the cost to operate a service profitably and the price presented to the user is very complex, so just because the price happens to be x right now doesn't tell you much. For example, something like 30% of the price of an iPhone is markup.

> while having a longer wait time for a car

Obviously incidental?

> It also couldn’t operate on the highway so the transit time was nearly double.

Obviously easily fixable?

> One shouldn’t underestimate how economical real human operators are.

There's nothing to underestimate, human drivers don't scale the way software drivers do. It doesn't matter how little humans cost, they are competing with software that can be copied for free.

> Waymo can’t share the business expense of their vehicles with their employees

They can share parking space, cleaning services, maintenance, parts for repair, etc.

> I’m sure it’ll improve but this tells me that Waymo’s price per vehicle including all the R&D expenses must be astronomical.

Obviously, they're in the development phase. None of this matters long term.

> They are burning $2 billion a year at the current rate even though they have revenue service.

"The stock market went up 2% yesterday so it will go up 2% today too and every day after that."

> Plus, they actually have a lot of human operators to correct issues and talk to police and things like that.

Said operators are shared between all vehicles and their number will go down over time as the driving software improves.

---

To sum up, every single part of what Waymo is trying to do scales. Every problem you've mentioned is either incidental or a one-off cost long term.

dangus

The number one tech bro blind spot is the assumption that everything in the physical world scales with software and that every business and type of cost benefits greatly from economies of scale and the removal of human labor.

There are a great number of examples where that’s not true. Cookie store chains like Crumbl are a really good example. All the economies of scale stuff with them backfires. The product is too low price and too simple to make in batches, so the businesses with the best margins are ones that avoid traditional brick and mortar rent and don’t hire employees.

In the same way, an uber or taxi’s labor cost seems like it’s a huge scaling problem that needs to be resolved but really think about the costs involved with creating that scale to replace them.

Let’s not forget that at Waymo they still need a human to clean, fix, and charge/gas up, interact with customers and police, resolve driving edge cases, etc, all costs that a human driver essentially includes with their pay and does for “free.” Then you’ve got car storage and the capital expense of the vehicle that the uber driver heavily subsidizes and splits between business and personal use.

Basically, Waymo is looking to compete using their very complex and sophisticated solution in a market where its competitors are hiring lowest bidder temporary contractors.

agildehaus

Both the longer wait time and the double price can likely be explained by the lack of highway.

Highway is coming.

And scale will make it cheaper. It's only cheaper than Uber sometimes currently. That will change.

dangus

Will it change?

Uber drivers are already paid low wages and any price competition can lower their wages further.

Waymo has to pay for things that “come with” uber drivers: the cars, storage for the cars, employees to clean and maintain the cars, extra infrastructure to support the self driving cars like cellular data for each car, data centers, engineers, customer service to interact with police and resolve edge cases (will never go away). Waymo also has to pay all these people healthcare benefits and pay W2 payroll, not a thing for Uber.

Waymo is like a professional moving company competing on price with an army of lowest bidder independent contractors who already have a beat up graffiti van.

whyenot

My experience using Waymos in SF is that they are a little less expensive than an Uber. The other advantage is that you aren't stuck with a driver who hits on you or wants to share his opinions on the best way to slaughter goats.

muchosandwich

I've also had an Uber driver talking about butchering various farm animals. I vastly prefer Waymo because it's a much calmer experience.

acchow

Waymo is significantly more expensive than UberX nowadays. People are happily willing to pay for the better experience (and tourists probably the novelty)

dangus

And uber is profitable. Waymo burns $2 billion a year.

Ferret7446

> One shouldn’t underestimate how economical real human operators are

That's such a silly statement. One shouldn’t underestimate how UNeconomical real humans are.

In the past 12,000 years, human efficiency has improved, maybe, 10x. In the past 100 years, technological efficiency has improved, maybe, 1,000,000x.

Any tiny technological improvement can be instantly replicated and scaled. Meanwhile, every individual human needs to be re-trained and re-grown. They're extremely temperamental, with expensive upkeep, very short lifespans and even shorter productive lifespans.

In fact, humans have improved so little, that every time, they scoff at the new technology and say it will never take off, and they're still doing it 12,000 years later, right now, right above this post.

consteval

The misconception here is that technology just magically runs on its own.

No, it’s created by and maintained by humans. You’re shifting the cost of a driver to software engineers, data analysis, people mapping out roads, etc.

This is why Uber doesn’t make any money, despite being more expensive for the customer as compared to traditional taxi services. Coordinating Ubers across the country costs a lot of servers and a lot of engineers. Sure, the system is automatic - maintaining it isn’t.

So you end up with a lose-lose-lose scenario. The ride is more expensive for the customer. The driver makes less money. And Uber bleeds hundreds of millions a year.

Technology is neat, yes, but often we don’t stop and think “wait… does this make sense?”

We don’t know if autonomous cars make any economic sense. They could end up not. It doesn’t help that 99% of tech companies in the transportation space are just making trains with extra steps. Like, guys - have we even done feasibility analysis?

TulliusCicero

I mean yeah, right now they've hit the point of being quite safe, but they're not necessarily as fast as human drivers. They'll keep making incremental progress and will get there eventually, probably.

So far, every time there's been self driving car progress, someone's been like, "okay yeah, but can they do <the next thing they're working on> yet??" like some weird gotcha. Tech progress is incremental, shocking I know.

VirusNewbie

In LA, wait times were the same as Uber and the price was the same as well (for a nicer car some of the time).

ajmurmann

I've used Waymo in both LA and SF and lived it. However, wait times in LA varied hugely. Downtown LA one evening was over twenty minutes and a few hours later less than five. I wonder if they just don't have enough vehicles there and because it's such sprawl it can easily happen that no car is nearby.

Zigurd

That's the correct indicator to look for: the number of Waymos on the road is still very small compared to the number of other vehicles. Alphabet wouldn't risk the cost of expanding to the current number of cities without very strong confidence that they're not going to lose their shirt doing it.

The evidence so far is that they are throttling demand by keeping the prices above that of an Uber. It's definitely still an experiment. If the experiment is successful, expect to see more cities and more vehicles in each city in expanding service areas.

There are step changes that have to be made to keep waymo expanding. The tariff situation is blocking plans to have dedicated vehicles from China. That has to get sorted out. The exact shape of the business model is still experimental.

Of course it's got to be safe. But there are dozens of dull details that all have to work between now and having a profitable business. The best indicator of a plausible success is that Waymo appears to be competent at managing these details. So far anyway.

happyopossum

> The evidence so far is that they are throttling demand by keeping the prices above that of an Uber.

I've only been in a handful of Waymo rides, but in each case it's been about half the price of an Uber.

Zigurd

Having taken a closer look, it's at least a mixed bag. There doesn't seem to be a definitive policy to manage demand by keeping the price high.

asielen

This has been my experience also, especially considering no tipping.

londons_explore

> One of the drivers had 56 near crashes and 4 actual crashes in less than 20K miles!

There would be a strong argument to simply banning the worst 1% of drivers from driving, and maybe even compensating them with lifetime free taxi rides, on the taxpayers dime.

jillesvangurp

Nah, just revoke their licenses and make it much harder to get one to begin with. Autonomous driving removes the economic necessity of having one. Just get a proper car that can drive you to work. No need for you to do anything. Catch up on lost sleep (a common cause of accidents is people being to tired to drive) or whatever.

Expect to pay for the privilege of driving yourself and putting others at risk. If you really want to drive yourself, you'll just have to skill up to get a license and proper training, get extra insurance for the increased liability, etc. And then if you prove to be unworthy of having a license after all, it will be taken away. Because it's a privilege and not a right to have one and others on the road will insist that you are competent to drive. And with all the autonomous and camera equipped cars, incompetent drivers will be really easy to spot and police.

It will take a while before we get there; this won't happen overnight. But that's where it's going. Most people will choose not to drive most of the time for financial reasons. Driving manually then becomes a luxury. Getting a license becomes optional, not a rite of passage that every teenager takes. Eventually, owning cars that enable manual driving will become more expensive or may not even be road legal in certain areas. Etc.

trollbridge

Lower income people, in the U.S., tend to live in cheap areas and use a car to access employment in an hour+ radius. Making driving expensive for them simply means limiting their employment or cutting them off from it entirely.

Driving should not be a privilege exclusively for rich people. Poor people cannot afford to pay an Uber to drive them around and can’t afford to buy some Tesla with FSD either. Waymo would be grossly unaffordable for a 120 mile daily round trip commute.

In Australia I met people with even longer commutes - going 150km to get to a job, mostly due to how unaffordable housing has become.

If you want to take away people’s cars, you need to make sure they can access employment and have affordable, safe housing. Remember that half the population makes less than the median income.

danaris

> Autonomous driving removes the economic necessity of having one.

...Once autonomous cars can go everywhere human-driven cars can, in all the conditions humans can drive in.

Remember that Waymo is still very restrictive in where they choose to operate.

gambiting

>>Nah, just revoke their licenses and make it much harder to get one to begin with

I 1000% agree with you, but unfortunately in some countries like the US that kind of argument leads to nowhere, because people think driving is a human right and also the entire country is built around having a car so you are actually truly screwed if you don't have one.

>> Autonomous driving removes the economic necessity of having one. Just get a proper car that can drive you to work.

Sure, except it doesn't exist and I honestly doubt it ever(in the next 50-100 years) will. If you need autonomous driving that takes you to your destination that already exists though - it's called a taxi.

ChrisMarshallNY

Someone from Germany could confirm or correct this, but I have been told that if you get a DUI in Germany, your driver’s license is toast —for good.

eptcyka

Perverse incentives will just balloon the bad driver population. Funny, since the brits have a history with these kinds of things.

allan_s

Yes something like free bus card and N kilometers of taxi fares per month, so that :

1. People who normally take the bus are not incentivise to get their driving license /make a big accident

2. People already driving are still blt rewarded ,just not blocked

3. One may argue that if some of the borderline "not that dangerous but still..." driver do it on purpose to cross the line it still may benefits soxiety economically wise

n4r9

Hang on, why are brits suddenly being mentioned?

pc86

You don't have a right to free transportation.

I'd immediately donate money to and vote for any politician stupid enough to say we should revoke licenses from the worst 1% of drivers.

Revoke their licenses, let them figure it out. Get a ride from friends. Take the bus. Move closer to work. You're a danger.

If they break the law and drive anyway, put them in jail.

ryandrake

> If they break the law and drive anyway, put them in jail.

They are going to drive anyway, because in most of the USA, you need a car to get basically anywhere, including to work. So now instead of just being a bad driver, they're also unemployed and sitting in jail, which taxpayers are paying for. There are people with dozens of DUIs, totally uninsurable, their licenses pretty much permanently revoked, and they still drive every day.

HamsterDan

Great idea. And people who start fires while cooking should be given free private chefs too.

akoboldfrying

It really depends on whether there's shame attached, which isn't easy to control.

A private chef sounds good to me; having to go and collect specially marked "safe" meals at the supermarket with a card that's only given to adults the state deems incapable of looking after themselves, not so much.

mattlondon

It kinda works already without outright banning them: the mandatory insurance will get more and more expensive the more accidents they have.

So they price themselves out.

Of course, they may then decide not to have insurance at all. In most countries that is illegal and doing that in a premeditated way is criminality and something else entirely.

Not sure if insurance is mandatory in the US or not - I assume instead you just get into a gunfight with the other party instead?/s

amy_petrik

Not sure if insurance is mandatory in the US or not

It's mandatory and requiring proof when you register your car. Your insurer also has a line to the DMV (car registration government) to say, "FYI this guy is not insured" and the DMV gets mad.

It's a known problem, particularly with undocumented peoples, that they are often uninsured. California studied the issue: https://www.insurance.ca.gov/01-consumers/105-type/95-guides...

In the report California states up to 13% of the US residents of some areas do not happen to possess documentation documenting their legality of being in the US. Often they came from countries with no insurance requirement, so they are unaware of American culture and policies in this regard. The report also states 10% of drivers are uninsured. I'm not sure why the DMV isn't getting mad in this case, being informed the car is not insured. So it's "mandatory" but 10% of drivers are not insured. Similar to how in California retail theft is technically "illegal" but a lot of people will do that without consequences. Honestly if you ask me we need to be waiving the insurance requirement for cultural reasons and take a verbal Spanish-first policy to help accommodate people who have undocumented English skills or are without documentation of being literate.

londons_explore

1 issue is insurance doesn't pay out much for road deaths.

Government generally budgets deaths at $3M-$30M per person killed. Yet a car accident that kills someone usually doesn't result in any payout at all.

That in turn means insurance companies are offering risky people lower rates than economists would suggest for the societal cost/risk.

londons_explore

If you're having an accident costing $10k twice a year, your insurance ought to cost at least $20k/year.

But for whatever reason, it seems such people end up with far lower (yet still expensive) insurance quotes at more like $4k/year.

trollbridge

It’s mandatory. That doesn’t stop people from driving a relative’s car with no insurance. Or driving with expired tags.

Good luck if such a person hits you; they’ll simply drive off. Recently a friend of mine had a fender bender with someone else, most likely his fault. That person didn’t have a valid registration or insurance and wasn’t at fault but begged to just go without calling the police. My friend handed them the cash out of his pocket since he felt bad for damaging their car, but they did NOT want to see the police.

The only way to enforce not having expired tags/no licence/no insurance is strict police enforcement. A lot of Americans don’t like that and so police agencies end up being lenient, preferring to focus on more violent crimes instead of just trying to pull every car with expired tags over.

steveBK123

Wait until you hear about the post-COVID rates of lawlessness in the US with uninsured and/or unlicensed drivers on the road..

pc86

> 4 actual crashes in less than 20K miles

Sorry if you're having a car crash every 6 months or less, you shouldn't have a license.

Driving a car is privilege granted to you by your state, and this state is negligent in its protection of everyone else by letting this idiot continue to drive. Sell your car, take the bus, move closer to work, I don't care.

More than 3 at-fault crashes in a year or more than 10 at-fault crashes ever and you should permanently lose your license forever. That seems more than generous enough.

derf_

> Sorry if you're having a car crash every 6 months or less, you shouldn't have a license.

Actual traffic enforcement does not seem to produce this result. This woman is fairly famous on Reddit for her erratic driving, and was reported in 2019 as having been involved in 31 crashes since 2000: https://www.wral.com/story/lawyer-stayumbl-driver-a-victim-o...

She is still driving (with a new license plate after 2019): https://old.reddit.com/r/bullcity/comments/1ji3y82/jesusdos_...

eightysixfour

There is already a mechanism for this that the government doesn’t even have to be directly involved in - insurance. At some point you become prohibitively expensive to insure.

However, the government still has to do its part and actually enforce insurance requirements.

My pet hypothesis is that there is a tipping point where the feedback loop between driver safety, ai advancements, and insurance costs will doom manually driven cars faster than most people think.

nomel

> At some point you become prohibitively expensive to insure.

This would probably just cause more uninsured drivers. For California, that's around 17% [1]!

[1] https://www.iii.org/fact-statistic/facts-statistics-uninsure...

magicalhippo

Here in Norway we've got a point system[1], and I'm sure we didn't invent it.

Each point lasts for 3 years, and if you accumulate more than 8 you lose your license for 6 months.

A speeding ticket is at least two points, and running a red light or tailgating is three for example. You get double points the first two years after getting your license.

potato3732842

It's probably some old "bingo and church" driver who has a 50-50 shot of winding up in the ditch if it snows during Bingo and that "20k" is actually "8yr", the kind of thing insurance would never know about if you're not getting towing coverage through them.

jonplackett

Is Waymo doing ‘easier’ miles than an average human in any way? How limited is their range and types of roads they’ll use?

danaris

Yes, vastly easier.

As I understand it, they limit their range to a few cities in the American Southwest and West Coast, and don't operate in bad weather.

mdeeks

Waymo definitely operates on bad weather. In fact, that is when I use it most since I don't want to walk or bike in the city when its pouring. The wait times are longer on those days.

City driving is very chaotic. Though speeds tend to be lower so likely accidents would be just fender benders. They don't operate on freeways.

Waymo claims to operate in fog and rain since 2021: https://waymo.com/blog/2021/11/a-fog-blog

motorest

> Serious crash rates are a hockey stick pattern. 20% of the drivers cause 80% of the crashes, to a rough approximation. For the worst 20% of drivers, the Waymo is almost certainly better already.

I would wager that those 20% of drivers also are disproportionally under the influence of drugs, impaired in any way (i.e., stroke, heart attack, etc), or experiencing sudden unexpected events such as equipment malfunction.

Defensive driving is risk mitigation.

MichaelRo

You forgot "being an idiot" and it's strange, because the vast majority of the accidents are caused by that. Have you never watched "idiots driving" videos on YouTube?

aziaziazi

Stupid behavior is not exclusive to being on drugs, heart attack or equipment malfunction though.

While I like watching those videos I suspect a fair share of them has a deeper explanation than "being an idiot”. But it’s a lot less fun to watch when you imagine the guy driving may be in a desperate position.

Btw the meaning of idiot is “someone ignorant". As contextless external watchers of a crash, the real idiots are probably you and me, the YouTube watchers.

timewizard

You'd be correct. At least as far as fatalities are concerned. 50% of all fatalities involve drugs or alcohol. Around 50% of all fatalities are single vehicle accidents though. 15% are motorcycles. 15% are pedestrians.

And of course around 80% involve youth, testosterone and horsepower in some combination. The rest are almost always weather or terrain related in some way. Massive pileups on the highway in the winter and upside down vehicles on waterways in the summer.

Very rarely does a fatal accident happen without several factors being present.

labrador

I was initially skeptical about self-driving cars but I've been won over by Waymo's careful and thoughtful approach using visual cues, lidar, safety drivers and geo-fencing. That said I will never trust my life to a Tesla robotaxi that uses visual cues only and will drive into a wall painted to look like the road ahead like Wile E. Coyote. Beep beep.

Man Tests If Tesla Autopilot Will Crash Into Wall Painted to Look Like Road https://futurism.com/tesla-wall-autopilot

bob1029

I started digging into this rabbit hole and I found it fairly telling how much energy is being expended on social media over LiDAR vs no LiDAR. Much of it feels like sock puppetry led by Tesla investors and their couterparties.

I see this whole thing is a business viability narrative wherein Tesla would be even further under water if they were forced to admit that LiDAR may possess some degree of technical superiority and could provide a reliability and safety uplift. It must have taken millions of dollars in marketing budget to erase the customer experiences around the prior models of their cars that did have this technology and performed accordingly.

x187463

I use FSD every day and it has driven easily 98% of the miles on my model 3. I would never let it drive unsupervised. I honestly have no idea how they think they're ready for robotaxis. FSD is an incredible driver assistance system. It's actually a joy to use, but it's simply not capable of reliable unsupervised performance. A big reason, it struggles exactly where you think it would based on a vision only system. It needs a more robust mechanism of building it's world model.

A simple example. I was coming out of a business driveway, turning left onto a two lane road. It was dark out with no nearby street lights. There was a car approaching from the left. FSD could see that a car was coming. However, from the view of a camera, it was just a ball of light. There was no reasonable way the camera could discern the distance given the brightness of the headlights. I suspected this was the case and was prepared to intervene, but left FSD on to see how it would respond. Predictably, it attempted to pull out in front of the car and risked a collision.

That kind of thing simply can not be allowed to happen with a truly autonomous vehicle and would never happen with lidar.

Hell, just this morning on my way to work FSD was going run a flashing red light. It's probably 95% accurate with flashing reds, but that needs to be 100%. That being said, my understanding is the current model being trained has better temporal understanding such that flashing lights will be more comprehensible to the system. We'll see.

labrador

Your report matches many other real world reports I've read. I'm pretty good at day dreaming or thinking while driving, so having to keep my hands ready to take over while being completely alert that FSD might error would be a big downgrade in my driving experience. I'd rather drive myself where my subconscious muscle memory does the driving so my conscious mind can think about other things. Having to pay attention to what FSD was doing would be a drag and prevent me from relaxing.

Nemi

And you trust that you will ALWAYS have the awareness of intervening if and when FSD does something life threatening? You are braver than I am.

I am willing to experiment in many ways with things in my life, but not WITH my life.

lnsru

Tesla sold a million Model Ys last year. So having a safety increasing part like lidar would reduce the profit by hundreds millions. Removal of ultrasonic sensors saved Tesla tens of millions. Ok, model Y is a big car and I don’t aim for tightest parking spots anymore. But basically removal of anything is very profitable for Tesla. And vice versa adding something useful is very expensive.

whamlastxmas

It’s saved hundreds of millions at minimum. LiDAR is incredibly expensive hardware which is why they’re making it work well without it - it would make the cost of the cars really uncompetitive while also looking incredibly silly like Waymos. No one would buy them

labrador

"It's a feature, not a bug!"

I suspect it would be a major undertaking to add LiDAR at this point because none of their software is written to use it

Just because Tesla uses shitty 2MP sensors of 2013 vintage (at least for HW3) doesn’t mean that robotaxi levels of safety can’t be achieved with just modern cameras and radars (plural)

As someone in the industry, I find the LiDAR discussion distracting from meaningful discussions about redundancy and testing

whamlastxmas

We all see our perspectives as getting quashed. I see the opposite of you - people pushing arguments that make no sense to me in terms of criticizing Tesla for not using lidar, which is an argument that seemingly deliberately glances over the very real and valid reasons for Tesla choosing not to use it

ggreer

Mark Rober's video is misleading. First, he used autopilot, not FSD. Second, he sped up to 42mph and turned on autopilot a few seconds before impact[1], but he edited the Youtube video to make it look like he started autopilot a from a standstill far away from the barrier. Third, there is an alert message on his screen. It's too small to read in the video, but it could be the "autopilot will not brake" alert that happens when you put your foot on the gas.

In the water test, Rober has the Tesla driving down the center of the road, straddling the double yellow line. Autopilot will not do this, and the internal shots of the car crop out the screen. He almost certainly manually drove the car through the water and into the dummy.

One person tried to reproduce Rober's Wile E. Coyote test using FSD. FSD v12 failed to stop, but FSD v13 detected the barrier and stopped in time.[2]

Lidar would probably improve safety, but Rober's video doesn't prove anything. He decided on an outcome before he made the video.

The first tweet I linked to is Mark Rober's unedited video of the crash. The second tweet I linked to is a video of someone trying to reproduce the Wile E. Coyote test. Unless you think the videos are faked (one of which was posted by Mark Rober), I'm not sure what objection you're making.

renewiltord

Videos on YouTube are also not a reliable source. But your demand for rigor seems rather isolated.

Ferret7446

A wall painted to look like a road would likely cause human accidents and the painter would be very much criminally liable for them.

That said, I do think using only visual cues is a stupid self-imposed restriction. We shouldn't be making self-driving cars like humans, because humans suck horse testicles at driving.

audunw

The painted wall was just a gimmick to make the video entertaining. What’s more concerning is the performance in fog, rain and other visually challenging conditions.

whamlastxmas

Reviews of the wall gimmick video also make it clear that the LiDAR car stopped because it detected the water, not the wall. And there are tons of videos of LiDAR cars coming to a complete stop in traffic because of steam from a manhole or light water spraying just off the side of the road. Also don’t get me started on the manufacturer of the lidar car being mark’s close friend, and had previously given mark millions of dollars for another project he did

x187463

I think the correct response for FSD would have been to stop in the situations presented in the video. That wasn't anything like normal fog, rain, or light obstruction. The situations they created were so extreme you simply couldn't operate a vehicle safely. That being said, the effectiveness and precision of lidar should be a legal requirement for autonomous vehicles.

consteval

In addition, humans have a lot of senses. Not just 5 - but dozens. A lot of them working in the background, subconsciously. It’s why I can feel someone staring at me, even if I never explicitly saw them.

timewizard

> because humans suck horse testicles at driving.

Hardly. We drive hundreds of billions of miles every month and trillions every year. In the US alone. You're more likely to die from each of the flu, diabetes or a stroke than a car accident.

If those don't get you, you are either going to get heart disease or cancer, or most likely, involve yourself in a fatal accident; which, will most likely be a fall of a roof or a ladder.

Ukv

Worldwide stats from https://www.who.int/news-room/fact-sheets/detail/road-traffi...:

> Approximately 1.19 million people die each year as a result of road traffic crashes.

> Road traffic injuries are the leading cause of death for children and young adults aged 5–29 years.

Falls from a ladder/roof do not come close to that as far as I've been able to find. They'd be a subset of falls from a height, which is a small subset of unintentional falls/slips, which is still globally under road accident deaths.

It's true that diabetes, strokes, heart disease, flu, etc. do cause more deaths, but we're really into the absolute biggest causes of death here. Killing fewer than strokes is the lowest of low bars.

I think there's also the argument to be made in terms of years of life lost/saved. If you prevent a road accident fatality, chances are that person will go on to live many more healthy years/decades. If you prevent a death by stroke, flu, or even an at-home fall, there is a greater chance that person is already in poor health (to have potentially died from that cause) and may only be gaining a few extra months.

Mawr

"1000C is not that hot, the Sun is hotter!"

If you have to reach that hard to make your point, it's not a great point.

Is 40,000 deaths every year a lot?

IMHO it kinda is. It's 13x as many people as died in 9/11

KoolKat23

To be fair, I'm sure there's a few humans that would crash into a giant painted road in the middle of a straight road in the middle of nowhere. Humans crash due to less.

Well, I wouldn't and neither would a Waymo, but a Tesla did, which means it's no better than a bad human driver

saurik

I think I might, and I'm surprised by how confident you are that you wouldn't.

Of course, that's why traffic accidents are called 'accidents.' Drivers wouldn't crash their cars, but they do.

ourmandave

To be more fair, some humans will drive into rivers if the gps map tells them to. =\

labrador

My conclusion: If Tesla drivers are comfortable with vision-only FSD, that’s fine — it’s their responsibility to supervise and intervene. But when Tesla wants to deploy a fully autonomous robotaxi with no human oversight, it should be subject to higher safety requirements, including an independent redundant sensing system like LiDAR. Passengers shouldn’t be responsible for supervising their own taxi ride.

UltraSane

It is truly astonishing how much Musk hypes up the robotaxi when no Tesla has ever driving a single mile autonomously while Tesla was liable for crashing.

If you can visually detect the painted wall, what makes you think that cameras on a Tesla can't be developed to do the same?

And are deliberately deceptive road features actually a common enough concern?

aoeusnth1

How about fog and rain?

Same as humans, drive slow enough that you can stop when you see something ahead. As demonstrated Lidar doesn't work in rain either.

Waymos choose the routes, right?

The issue with self-driving is (1) how it generalises across novel environments without "highly-available route data" and provider-chosen routes; (2) how failures are correlated across machines.

In safe driving failures are uncorrelated and safety procedures generalise. We do not yet know if, say, using self-driving very widely will lead to conditions in which "in a few incidents" more people are killed in those incidents than were ever hypothetically saved.

Here, without any confidence intervals, we're told we've saved ~70 airbag incidents in 20 mil miles. A bad update to the fleet will easily eclipse that impact.

arghwhat

> The issue with self-driving is (1) how it generalises across novel environments

That's also an issue with humans though. I'd argue that traffic usually appears to flow because most of the drivers have taken a specific route daily for ages - i.e., they are not in a novel environment.

When someone drives a route for the first time, they'll be confused, do last-minute lane changes, slow down to try to make a turn, slow down more than others because because they're not 100% clear where they're supposed to go, might line up for and almost do illegal turns, might try to park in impossible places, etc.

Even when someone has driven a route a handful of times they won't know and be ready for the problem spots and where people might surprise they, they'll just know the overall direction.

(And when it is finally carved in their bones to the point where they're placing themselves perfectly in traffic according to the traffic flow and anticipating all the usual choke points and hazards, they'll get lenient.)

mjburgess

People have eyes, ears, a voice, hands, etc.

You've a very narrow definition of novel, which is based soley on incidental features of the environment.

For animals, a novel situation is one in which their learnt skills to adapt to the environment fail, and have to acquire new skills. In this sense, drivers are rarely in novel environments.

For statistical systems, novelty can be much more narrowly defined as simply the case where sensory data fails a similar-distribution test with historical data --- this is vastly more common, since the "statistical profile of historical cases, as measured, in data" is narrow.. whilst the "situations skills apply to" is wide.

An example definition of narrow/wide, here: the amount of situations needed to acquire safety in the class of similar environments is exponential for narrow systems, and sublinear for wide ones. ie., A person can adapt a skill in a single scenario, whereas a statistical system will require exponentially more data in the measures of that class of novel scenarios.

arghwhat

I have a very wide definition of novel - any exact environment you have not yet traversed. First time taking that right turn? Novel route.

Out eyes, ears, voice and hands are quite useless when operated consciously.

harrall

I travel and drive in a lot of new places and even the novelty of novelty wears off.

At some point you’ll see a car careen into the side of the curb across three lanes due to slick and you’ll be like ehhh I’ll just cut through with this route and move on about your day.

After driving for 20 years, about the only time I got scared in a novel situation was when I was far from cell service next to a cliff and sliding a mountain fast in deep mud running street tires due to unexpected downpour in southern Utah. I didn’t necessarily know what to do but I could reason it out.

I don’t really find “using a new route” difficult at all. If I miss my exit, I’m just going to keep driving and find a U-turn — no point to stress over it.

arghwhat

Remember that what matters is the general driving populace, and there will always be people who drive better and who drive worse.

Also, a very significant portion of drivers overestimate their driving skills, in particular older drivers. Having only been scared once in 20 years would likely make someone lenient and dull their senses as nothing requiring notable effort or attention ever seems to happen to them.

npunt

Generalizing across novel environments is optimal, but I'm not sure the bar needs to be that high to unlock a huge amount of value.

We're probably well past the point where removing all human-driven vehicles (besides bikes) from city streets and replacing them with self-driving vehicles would be a net benefit for safety, congestion, vehicle utilization, road space, and hours saved commuting, such that we could probably rip up a bunch of streets and turn them into parks or housing and still have everyone get to their destinations faster and safer.

The future's here, even if it still has room for improvement.

floxy

>congestion

I'd think congestion would go up as AVs become more popular, with average occupancy rates per vehicle going down. Since some of the time the vehicle will be driving without any passengers inside. Especially with personally owned AVs. Think of sending a no-human-passenger car to pick up the dog at the vets office. Or a car circling the neighborhood when it is inconvenient to park (parking lot full, expensive, whatever).

npunt

Up to 30% of cars on city streets at any given time are looking for parking [1].

Cars are also the least utilized asset class, being parked 95% of the time [2].

AVs, by virtue of being able to coordinate fleet-wide and ability to park anywhere rather than only one's home or destination, would be able to gain incredible efficiencies relative to status quo.

Atop those efficiencies, removing both the constraint of having a driver and the constraint of excessive safety systems to make up for human inattentiveness means AVs can get drastically smaller as vehicles, further improving road utilization (imagine lots of 1- and 2-seaters zipping by). And roads themselves can become narrower because there is less room for error with AVs instead of humans.

Finally, traffic lights coordinating with fleets would further reduce time to destination (hurry up and finish).

Self-driving vehicles give us the opportunity to rethink almost all of our physical infrastructure and create way more human-friendly cities.

[1] http://shoup.bol.ucla.edu/PrefaceHighCostFreeParking.pdf

[2] https://senseable.mit.edu/unparking/

woah

Every city street would have 4 lanes without the need for free car storage. Maybe make one of them a bike lane or widen the sidewalks and have 3 lanes for 30% more capacity. Also, traffic engineering could be optimized to a much greater extent since you wouldn't have to worry about all the affordances which keep humans from getting confused, keep them from getting aggressive, keep them from speeding, etc. Also, most congestion is caused by drivers causing turbulence by switching lanes, stopping each other from switching lanes, getting in the wrong lane, etc. A city of only AVs would probably flow much more smoothly.

kccqzy

I don't agree with this novel environment argument about routes. As a human, there are a limited number of roads that I have driven on. A taxi driver drives better than me because none of the routes are considered novel: the taxi driver has likely driven on every road in a city in his/her career. The self-driving machine has most definitely driven on every single road in the city, perhaps first as testing with human backup, then testing with no passengers, and finally passenger revenue miles.

KoolKat23

I think you underestimate how many novelties the car will encounter on existing routes and how adept these cars are at navigating novel routes.

I imagine this route data is an extra extra safeguard which allows them to quantify/measure the risk to an extent and also speed up journey's/reduce level of interventions.

jrussino

I wonder if you can decrease the impact of (2) with a policy of phased rollout for updates. I.E. you never update the whole fleet simultaneously; you update a small percentage first and confirm no significant anomalies are observed before distributing the update more widely.

timschmidt

Ideally you'd selectively enable the updated policy on unoccupied trips on the way to pick someone up, or returning after a drop-off, such that errors (and resultant crashes) can be caught when the car is not occupied.

nukem222

Presumably management would also be highly regional. Functionality in san francisco doesn't imply anything about functionality in oakland, etc.

mjburgess

One measure of robustness could be something like: the ability to resist correlation of failure states under environmental/internal shift. Danger: that under relevant time horizons the integral of injury-to-things-we-care-about is low. And then "safety", a combination: that the system resists correlating failure states in order to preserve a low expected value of injury.

The problem with machines-following-rules is that they're trivially susceptible to violations of this kind of safety. No doubt there are mitigations and strategies for minimising risk, but its not avoidable.

The danger in our risk assessment of machine systems is that we test them under non-adversarial conditions, and observe safety --- because they can quickly cause more injury than they have ever helped.

This is why we worry, of course, about "fluoride in the water" (, vaccines, etc.) and other such population-wide systems... this is the same sitation. A mass public health programme has the same risk profile.

timewizard

You would save more lives by harshly punishing drunk or influenced driving; however, most of the lives you save would be that of the drinker or the abuser.

You would save more lives by outlawing motorcycles; however, it would just be the motorcyclists themselves.

Another thing people don't consider is that not all seats in a vehicle are equally safe. The drivers seat is the safest. Front passenger is less safe but still often twice as safe as sitting in the backseat. If you believe picking up your elderly parents and then escorting them in your backseat is safer than them driving alone you might be wrong. This is a fatality mode you easily recognize in the FARS data. Where do most people in a robotaxi sit?

Your biggest clear win would be building better pedestrian infrastructure and improving roadway lighting to reduce pedestrian deaths.

BalinKing

> Front passenger is less safe but still often twice as safe as sitting in the backseat

Is there a good source for this? I was always under the impression that it was the exact opposite….

timewizard

We've been improving front seat safety systems for years while not adding much in the back seat. The result is obvious in the fatalities data and many institutions have involved themselves in this problem. Here's one:

https://www.iihs.org/news/detail/new-crash-test-spotlights-l...

There are _so many_ bad assumptions about vehicle safety it honestly drives me nuts. Especially on Hacker News. The data is available from NHTSA in a database called FARS. I encourage everyone to go look through the data. You almost certainly believe several wrong things about driving and fatalities.

I think Elon Musk is exceptionally irresponsible for using these statistics in a flatly dishonest and misleading way. He wants to sell vehicles not truly educate you about safety. People should double check.

ogogmad

> In safe driving failures are uncorrelated and safety procedures generalise. We do not yet know if, say, using self-driving very widely will lead to conditions in which "in a few incidents" more people are killed in those incidents than were ever hypothetically saved.

Can you provide some examples of what you mean?

im3w1l

Volcanic eruption filling the atmosphere with ash. Acts of war or terrorism. Could be physical or cyberattack.

ogogmad

The only way for this to cause tens of thousands of death by self-driving alone is for people to suddenly need to drive the cars themselves, and not being able to do it well. Unless I'm missing something.

hmmm-i-wonder

Is crash the best indicator of success?

I know some really bad drivers that have almost no 'accidents', but have caused/nearly caused many. The cut off others, get confused in traffic and make wrong decisions etc...

Waymos, by media attention at least, have a habit of confusion and other behaviour that is highly undesired (one example going around a roundabout constantly) but that doesn't qualify as a 'crash'.

sbuttgereit

I expect that the media don't find stories of Waymos successfully moving from point A to B without incident nearly so compelling as those cases where that doesn't happen.

I experience Waymo cars pretty much every time I drive somewhere in San Francisco (somewhat frequent since I live there). Out of hundreds of encounters with cars I can only think of a single instance where I thought, "what is that things doing?!"... And in that case it was a very busy 5 way intersection where most of the human driven cars were themselves violating some rule trying to get around turning vehicles and such. When I need a ride, I can also say I'm only using Waymo unless I going somewhere like the airport where they don't go; my experience in this regard is I feel much more secure in the Waymo than with Lyft or Uber.

perlgeek

If you follow Utilitarian ethics, just ask yourself: how much (negative) utility do you assign to...

* a crash with a fatality

* a crash with an injury

* any crash at all

* a driverless car going around a roundabout constantly

for me, the answer is pretty clear: crashes per distance traveled remains the most important metric.

danaris

This is utterly missing the point of the parent.

Just because this car doesn't crash, that doesn't mean it doesn't cause crashes (with fatalities, injuries, or just property damage), and that's inherently much harder to measure.

You can only develop an effective heuristic function if you are actually taking into account all the meaningful inputs.

vpribish

Of course you are the best kind of correct but to instead advance the whole discussion I think we can agree that there is no trail of carnage in the wake of waymos leaving only them unscathed.

I live in sf. Waymos are far more predictable and less reckless than the meatwagons. They do not cause accidents with their occasionally odd behavior.

And to add another perspective - as a cyclist and pedestrian I put waymos even further ahead. I have had crashes due to misbehavior of cars - specifically poor lane keeping around curves - but waymos just don’t cause those sorts of problems

ajross

> Is crash the best indicator of success?

Well, yeah? Or rather, if it's not, then I think the burden of proof is on the person making that argument.

Even taking your complaints at their maximum impact: would you rather be delayed by a thousand confused robots or run over by one certain human?

potato3732842

>Even taking your complaints at their maximum impact: would you rather be delayed by a thousand confused robots or run over by one certain human?

Depending on the relative rates and costs of each type of mishap it could go either way. There is a crossover point somewhere.

The fact that you're coming right out the gate with a false dichotomy and appeal to emotion on top tells me that deep down you know this.

mlyle

> There is a crossover point somewhere.

I think his point is explicitly that that crossover point is rather high.

And let's not forget that crashes, in addition to their other costs, do cause significant delays themselves.

indiosmo

I suppose the argument is that while the robot itself might not have run over anyone, it might have caused someone else on the road to do it.

So if we're just measuring how many crashes the robot has been involved in, we can't account for how many crashes the robot indirectly caused.

ajross

> I suppose the argument is that while the robot itself might not have run over anyone, it might have caused someone else on the road to do it.

And I repeat, that's a contrived enough scenario that I think you need to come to the table with numbers and evidence if you want to make it. Counting crashes has been The Way Transportation Safety Has Been Done for the better part of a century now and you don't just change methodology midstream because you're afraid of the Robot Overlord in the driver's seat.

Science always has a place at the table. Ludditism does not.

ikerino

> Using human crash data, Waymo estimated that human drivers on the same roads would get into 78 crashes serious enough to trigger an airbag. By comparison, Waymo’s driverless vehicles only got into 13 airbag crashes. That represents an 83 percent reduction in airbag crashes relative to typical human drivers.

> This is slightly worse than last September, when Waymo estimated an 84 percent reduction in airbag crashes over Waymo’s first 21 million miles.

nitpick: Is it really slightly worse, or is it "effectively unchanged" with such sparse numbers? At a glance, the sentence is misleading even though it might be correct on paper. Could've said: "This improvement holds from last September..."

barbegal

Of course it's not worse, these numbers have huge error bars. Statistically the two statistics are not significantly different. But trying to explain that to most people with no knowledge of statistics is tough.

unreal6

One would hope that a writer on this subject would have at least a cursory knowledge of statistics

nukem222

83 vs 84 percent doesn't seem too difficult to present as "essentially the same". I also don't think this matters much—the result is impressive regardless of alleged rate of change.

0_____0

I wonder how many of those airbag crashes were an At-fault or shared-fault of the Waymo AVs.

MostlyStable

Assuming you trust Waymo's account, the article details them, saying the following:

>So that’s a total of 34 crashes. I don’t want to make categorical statements about these crashes because in most cases I only have Waymo’s side of the story. But it doesn’t seem like Waymo was at fault in any of them.

QuercusMax

Back when I used to pay attention to this stuff, the vast majority of crashes occurred when the Waymo vehicle was rear-ended while stopped at a traffic light.

onlyrealcuzzo

Considering that there's a >1000:1 ratio of regular cars to Waymo AVs - Waymo would have to be EXTREMELY terrible at driving to move the numbers for the other group meaningfully - which would show up in Waymo's own crash data.

There's also historical data. So if you saw a spike in crashes for regular vehicles after Waymo arrives, it would be sus. But there is no such spike. Further evidence Waymo isn't causing problems for non AVs.

Of course anything is possible. But it's unlikely.

MostlyStable

I'm confused by your comment. We shouldn't expect that Waymo accidents should budge overall accidents (which seems to be what you are talking about), but it wouldn't be crazy for Waymo, even if it was much safer overall, to be responsible for some non-trivial amount of all the accidents it has.

For example, imagine that Waymo is (somehow) far far far superhuman in it's ability to avoid other cars doing dumb/bad things. It has a dramatic reduction in overall accidents because it magically can completely get rid of accidents where the other driver is at fault. But, in some very specific circumstances, it can't figure out the proper rate to slow down at intersections, and it consistently rear ends vehicles in front of it. This specific situation is very rare, so overall accidents still are low (much lower than human drivers), but, in our made up, constructed (and extremely non-sensical) hypothetical, nearly 100% of Waymo accidents are Waymos fault.

So I don't think it's ridiculous to ask how many of the accidents Waymo has been involved in are the fault of the Waymo vehicle. It turns out that (assuming Waymo's side of the story is to be trusted), almost none of them are their fault, but it didn't have to be that way, even in the case where Waymo accidents were more rare than human accidents.

awongh

The number of miles driven seems large, but Gemini says there are thousands of crashes per day in the US- so 78 or 13 crashes is a really small sample size....

paxys

Worth repeating the same comment I've left on every variant of this article for the last 10 years.

Being better than "average" is a laughably low bar for self-driving cars. Average drivers include people who drive while drunk and on drugs. It includes teenagers and those who otherwise have very little experience on the road. It includes people who are too old to be driving safely. It includes people who are habitually speed and are reckless. It includes cars that are mechanically faulty or otherwise cannot be driven safely. If you compile accident statistics the vast majority will fall into one of these categories.

For self driving to be widely adopted the bare minimum bar needs to be – is it better than the average sensible and experienced driver?

Otherwise if you replace all 80% of the good drivers with waymos and the remaining 20% stay behind the wheel, accident rates are going to go up not down.

s1mon

Waymo (at this time) is an alternative to taxis and ride hailing services. I've lived in SF for 30+ years and used all modes of transit here. Some of my most frightening moments on the road have been in taxis with drivers who are reckless, in badly maintained vehicles, sometimes smelling of booze. There are certainly other ways that taxis could have been improved, but given the way things have evolved (or devolved with taxis), I feel much safer in a Waymo.

Any comparison of Waymo's safety should be done against taxis/Uber/Lyft/etc. A comparison with the general driving public could also be interesting, or other commercial drivers, but those are not the most relevant cohorts. I don't know the numbers, but I wouldn't be surprised if taxis/Uber/Lyft are worse per mile than general drivers since they are likely under more stress, and often work for long hours. A Waymo is no less safe at 4am, but a Lyft driver who's been up all night is a lot less safe. I would also guess that they are less likely than the general (auto) driving population to own their vehicle. Depending on who owns a vehicle, how long they've been driving (years), there's going to be a lot of interesting correlations.

D-Coder

But... that's the reality. If we replace human drivers with self-driving cars at random, or specifically the bad drivers above, then we've improved things.

We are not going to easily improve the average human driver.

Barrin92

>If we replace human drivers with self-driving cars at random

But that's the OPs point, we aren't. Waymo crashing less than human drivers is a tautological result because Waymo is only letting the cars drive on roads where they're confident they can drive as well as humans to begin with.

If you actually ran the (very unethical) experiment of replacing a million people at random on random streets tomorrow with waymo cars you're going to cause some carnage, they only operate in parts of four American cities.

danielbln

I think if you swap a million humans into other humans at random you're going to get some road carnage as well, to be fair. If someone suddenly puts me on some icy road in Minnesota I'm gonna have a bad time.

floxy

Why wouldn't alcoholics and the elderly be early adopters of self-driving vehicles. Or what can we do to encourage them to be early adopters? You get a DUI, and you are forced to pay for FSD? Get a reduce rate on booze taxes if you "drive" an AV? Have to take a driving test every 2 years after you turn 75, unless you have an AV?

paxys

"XYZ demographic should be forced to use self driving cars" is a fantasy that the tech crowd continues to believe but will never happen. Everyone is able to drive and will continue to be able to drive. In fact you should assume that the worse someone is at driving the more likely they are to want to drive for themselves, because that's how the world usually works.

potato3732842

I think it's the inverse. The people who are left lane camping in their Fiat 500 because the right lane has merging and that's scary will be the early adopters. The people who really "get it" will keep driving themselves because they can do better.

This is basically the same adoption path as every other labor saving tech.

aithrowawaycomm

Even in self-driving, Telsa's behavior proves there is a market for cars that are programmed to speed and roll through stop signs. Waymos are safer than the average human, but the average human also intentionally chooses a strategy that trades risk for speed. Indeed, Waymo trips on average take about 2x as long as Ubers: https://futurism.com/the-byte/waymo-expensive-slower-taxis

What happens if an upstart self-driving competitor promises human-level ETAs? Is a speeding Waymo safer than a speeding human?

senordevnyc

Over the next decade or two, insurance will solve a chunk of this problem (it'll be way more expensive to drive yourself), regulations will solve another chunk, but the biggest thing that will solve it: we're lazy.

We might drive every now and then, but come on, do you really think once this is ubiquitous and you can get in a (or your) car and then play a video game, take a nap, text on your phone, or doomscroll, that we're still going to want to drive all the time?

Nah.

potato3732842

Accident statistics are not dominated by drunks or anything else.

They're dominated by normal drivers who had a momentary lapse in judgment or attention. This is why running a police state that goes hard on DUI and vehicle inspections doesn't make the roads as much safer as its proponents would leave you to believe.

You say that and yet many places have an order of magnitude less car "accidents" per population than the US currently.

Nice Freudian slip there.

Rich western europe has less car accidents because they, broadly speaking, don't let poor people drive and work harder to cultivate a law abiding populace.

Great points. My own "have to say this every time" is that Waymo only operates within the boundaries of a few cities. Most people's experience of self-driving cars is not with Waymo. It's with vastly inferior technologies, most especially Tesla's. Waymo might be great, but I get really tired of fans dismissing others' misgivings as some sort of Luddite thing when it's entirely justified by experiences people have had where they live. If people want to say that autonomous vehicles are already better, they need to stop sneering long enough to show how that works at a freeway interchange with multiple high-speed merges and lane drops back to back, at a grocery store parking lot when it's busiest, near any suburban school at pickup time. Without that data, "safer than humans" is mere cherry picking.

Retric

There’s no statistics for how much a sensible and experienced driver crashes.

Sorting people by past behavior runs into survivorship bias when looking back and people who stop being sensible going forward. I’m personally a poor driver, but I don’t drive much so my statistics still look good.

IneffablePigeon

There’s _no_ statistics? Surely those statistics are precisely what all car insurance premiums are based upon. They might be proprietary but I am certain such statistics exist.

Retric

The best bucket insurance companies can use is based on age, car choices, and past behavior etc. Yet, a percentage of such people still end up in deadly accidents because they drove drunk, or while looking at their phones and such.

Insurance companies can’t know your future behavior so must hedge for a percentage of future idiots being in any bucket. On the flip side some people in the multiple DUI bucket end up driving sensibly over the next 6 months.

kccqzy

What kind of dataset do we have to determine the subset of accidents caused by sensible and experienced drivers?

I personally have doubts as to whether this dataset exists. Whenever there's an accident, and one party is determined to be at fault, would that party be automatically considered not to be a sensible driver?

If we don't have such a dataset, perhaps it would be impossible to measure self-driving vehicles against this benchmark?

> Otherwise if you replace all 80% of the good drivers with waymos and the remaining 20% stay behind the wheel, accident rates are going to go up not down.

That's a ridiculous scenario. If anything, impaired drivers should be more likely to choose an automated driving option. But no need to to even assume that. The standard that matters is replacing the average.

myflash13

I have always distrusted Waymo's and Tesla's claims of being safer. There are so many ways to fudge the numbers.

1. If the self-driving software chooses to disengage 60 seconds before it detects an anomaly and then crashes while technically not in self-driving mode, is that a fault of the software or human backup driver? This is a problem especially with Tesla, which will disengage and let the human takeover.

2. When Waymo claims to have driven X million "rider only" miles, is that because the majority of miles are on a highway which are easy to drive with cruise control? If only 1 mile of a trip is on the end-to-end "hard parts" that require a human for getting in and out tight city streets and parking lots, while 10 miles are on the highway, it is easy to rack up "rider only" miles. But those trips are not representative of true self driving trips.

3. Selective bias. Waymo only operates in 3-4 cities and only in chosen weather conditions? It’s easy to rack up impressive safety stats when you avoid places with harsh weather, poor signage, or complicated street patterns. But that’s not representative of real-world driving conditions most people encounter daily.

The NTSB should force them to release all of the raw data so we can do our own analysis. I would compare only full self-driving trips, end on end, on days with good weather, in the 3-4 cities that Waymo operates and then see how much better they fare.

Don't conflate Waymo and Tesla. Tesla FSD is by and large garbage, while Waymo is the real thing. Specifically:

1. Waymo is autonomous 100% of the time. It is not possible for a human to actually drive the car: even if you dial in support, all they can do is pick from various routes suggested by the car.

2. No, I'd guesstimate 90%+ of Waymo's mileage is city driving. Waymo in SF operates exclusively on city streets, it doesn't use the highways at all. In Phoenix, they do operate on freeways, but this only started in 2024.

3. Phoenix is driving in easy mode, but San Francisco is emphatically not. Weatherwise there are worse places, but SF drivers need to contend with fog and rain, hilly streets, street parking, a messy grid with diagonal and one-way streets, lots of mentally ill and/or drugged up people doing completely unpredictable shit in the streets, etc.

whamlastxmas

Humans remotely operate Waymos all the time. And humans routinely have to physically drive to rescue Waymos that get stuck somewhere and start blocking traffic, and famously had like 12 of them blocking a single intersection for hours.

If you think FSD is garbage then you’ve clearly never used it recently. It routinely drives me absolutely everywhere, including parking, without me touching the wheel once. Tesla’s approach to self driving is significantly more scalable and practical than waymo, and the forever repeated misleading and tired arguments saying otherwise really confuse me, since they’re simply not founded in reality

decimalenough

Waymo does not have remote operation capability. Here's a blog post from them explaining how "fleet response" works:

https://waymo.com/blog/2024/05/fleet-response/

It's possible to put the car in manual mode, but that requires a human behind the wheel.

I have a Tesla myself, and while it's a great car, it's a long, long way from actual autonomous driving and their own stats bear this out: it can manage 12-13 miles without driver interruption, while Waymo is clocking ~17,000. Hell, where I live, Autopilot can barely stay in lane.

kmacleod

How do you get yours to drive into a parking lot and park correctly? My HW4/v13.2.8 gets indecisive and ignores lines when getting to a destination. I always have to disengage before I can use parking mode.

> The NTSB should force them to release all of the raw data so we can do our own analysis.

No need. Waymo releases raw data on crashes voluntarily: https://waymo.com/safety/impact/#downloads

They also compare with human drivers only in places they operate and take into account driving conditions. For example, they exclude highway crashes in the human benchmarks because Waymo does not operate on highways yet.

Waymo is open about their comparison methodology and it would be helpful to read it (in the same link above) instead of assuming bad faith by default.

Tesla, on the other hand, is a completely different story.

shadowgovt

One of the more interesting things Waymo discovered early in the project is that the actual incidents of vehicle collision were under-counted by about a factor of 3. This is because NHTSA was using accident reports and insurance data for their tracking state, but only 1/3 of collisions were bad enough for either first responders or insurance to get involved; the rest were "Well, that'll buff out and I don't want my rates to go up, so..." fender-taps.

But Waymo vehicles were recording and tracking all the traffic around them, so they ended up out-of-the-starting-gate with more accurate collision numbers by running a panopticon on drivers on the road.

* In cities where weather is not a major contributing factor to crashes.

Seriously, don't make these statements until you have data against drivers in Toronto or Chicago or Boston or NYC. Humans in snow, freezing rain, ice, and thick fog still wins against your AI. Show me the data stating otherwise or address the data cherry pick.

perlgeek

It's the responsible thing to start in the best possible conditions, and slowly, slowly work yourself to harder conditions, only moving to the next step when the safety data from the previous step is better than human drivers.

Of course that means you don't have the data to compare Waymos with NYC drivers. Yet.

This article neatly summarizes Waymo’s latest safety numbers, but Waymo’s site provides much more detail, including a full breakdown of their comparison methodology: https://waymo.com/safety/impact/

But can they drive as aggressively as human drivers can? (which does probably increase accident rates a bit, but also can make rides 10-20% faster, especially if executed by an automated system that needs less safety margin)

1. Go as fast as possible without getting fines, violating speed limits whenever it's very likely to not be fined, doing maximum acceleration as needed (the latter configurable by the latter)

2. When there's congestion on the lane they need to take, take a free lane instead and then merge into the correct lane at the last possible opportunity, effectively skipping the queue

3. Run red lights when it can determine there is no enforcement camera on the traffic light, no police and no traffic

4. Aggressively do not yield to pedestrians unless unavoidable on crosswalks, swerving on the lane going the opposite direction as needed if pedestrians are on the side the vehicle is in

5. Aggressively pass slower drivers using opposite-direction lanes even when forbidden as long as the software can determine that it can reenter the lane before colliding with incoming traffic

6. Use barred parts of the road including sidewalks to bypass traffic when it's feasible to do so

7. Aggressively flash lights and tailgate on highways when on the fastest lane but behind a slower vehicle

8. When an emergency vehicle passes by, follow it closely to take advantage of its right of way

9. Aggressively do U-turns even when forbidden if it is determined to be possible

10. Ignore stop signs when it can see there is no traffic, and when it can't determine that plan to do maximal braking at the last moment if it sees any (the maximum braking needs to be rider configurable)

I used to take the same route regularly (with little traffic) and started timing myself. Speeding like a maniac in a decent car maybe got me there in 27 minutes instead of 30. I concluded it wasn’t worth it to speed or drive aggressively at all.

Well, until I drove a Dodge Charger R/T for a week. I could get there in 15 minutes. It had insanely good handling, amazing braking (enabling more aggressive driving), and absurd acceleration and handling at high speeds.

I concluded that was the last thing I needed and I drive a 50mpg Beetle now.

j_bum

30 min -> 15 min is absolutely frightening lol.

But agreed on your first part. When I actively rush to get home, but have the car I passed 10 mins ago show up behind me at a stoplight, it makes me realize it’s not worth it.

I view traffic as a form of a packet delivery system with a bit of time tolerance in either direction. Trying to rush through is fruitless and dangerous.

But you saying you cut your drive by 50% makes me question everything! Is it a busy commute?

trollbridge

Had lots of tight curves on it and quite a few places where you’d stop for a stop sign and then start up again. Fast engine = rocket off from those starts. Good handling = don’t need to decelerate in the curves.

breckenedge

I recently took an Uber ride like this and can’t say it was pleasant. I’d rather the drive be 10-20% slower. When I’m riding in an Uber I’m often multitasking, and sudden acceleration or braking makes that pretty difficult.

sublinear

> 9. Aggressively do U-turns even when forbidden if it is determined to be possible

Just doing this until out of gas sounds like the easiest way to satisfy these constraints.

I wasn't going to comment, but I couldn't get this image out of my head nor stop laughing.

IshKebab

> but also can make rides 10-20% faster

There's no way you're getting anywhere near 20% faster journey times by driving faster, unless you are seriously speeding and only travelling on motorways/highways.

ninkendo

I used to ride a motorcycle in the Bay Area and could get to work in less then 20 minutes, where a car would usually take me 60.

Lane splitting, driving 100mph when there’s enough space to do so, and generally being a maniac can get you places pretty quick. It can also pretty quickly make you dead. I survived 8 years of this commuting but I’d never do it again.

The idea that everyone has their own "public transportation" (a computer chauffeur) seems lacking in foresight.

I suspect, but don't know, that buses are safer still? (Not aware of any airbags triggering, ha ha.)

doctorpangloss

> The idea that everyone has their own "public transportation" (a computer chauffeur) seems lacking in foresight.

How so? As you increase the density of stops in a bus network and increase the rate of arrivals, there will be fewer passengers per bus, going on journeys that approach the fastest they could be. Why look at the one thing that has a really good chance of "fast, cheap and good" and say, "lack foresight?" My dude, it's the only game in town!
