Show HN: Report idling vehicles in NYC (and get a cut of the fines) with AI

·June 22, 2025

New York City has this cool program that lets anyone report idling commercial vehicles and get a large cut of the fines [1]. It's been in the news recently [2].

I've filed a few reports, and I found the process frustrating and error-prone. The forms are fiddly, there's way too much information that needs to be copied down from the video by hand, you have to use a third-party app to take a timestamped video and a different app to compress it before uploading, and approximately none of it can be done on your phone — the device you probably used to record your video in the first place.

I built Idle Reporter to make filing complaints into a five-minute process that you can do entirely from your phone.

Idle Reporter uses AI to automatically extract all the required information and screenshots from the video and fill out the form for you. It compresses your video, adds the required screenshots, and uploads the whole thing to DEP. All you have to do is log in, give it a final check, and submit.

The AI features cost me money to run, so I put those behind a subscription ($5.99/month, which can pay for itself after a single report). There's a one-week free trial so you can test it out. All the other features — including a fully-featured timestamp camera, which other apps charge for, and an editor for filling out the forms manually and submitting in a single step — will be free forever, as a service to the community.

The app is iOS-only for now — part of this was an exercise in learning SwiftUI in my spare time.

Check it out on the App Store and let me know what you think!

Spying on your friends, neighbors, and family? Nothing to see here, just old Soviet style repression tactics.

kennywinker

I understand the sentiment, but if you accept the premise that idling vehicles harm everyone, which they probably do - via air quality, foreign wars to keep oil flowing, and climate change - then why should we not fine the heck out of anybody who harms us all?

Don’t like getting reported by randos with apps? Don’t idle.

My only beef with the law itself, is that the fines need to be income-linked - otherwise it’s only illegal if you’re poor.

tptacek

These are people spying on commercial vehicles abusing rights of way to avoid paying their fair share of the cost to carry them in the area (parking, in particular). Why are you taking the side of the trucks?

tootie

Idling trucks are a public health hazard. Reporting actual crimes isn't spying. Certainly not when it's on public streets.

userbinator

Orwell was right.

kennywinker

You mean when he said “Every line of serious work that I have written since 1936 has been written, directly or indirectly, against totalitarianism and for democratic Socialism, as I understand it.” or something else?

CamperBob2

Not really. He thought the regime would have to use force. He didn't predict that people would line up outside Wal-Mart at zero dark thirty on Black Friday morning to grab the latest, greatest telescreen models, and then fight each other like dogs for the last ones in stock.

This is a phenomenal application of how fine-based bounties can be used to rapidly improve compliance with the law. Incredible work. I would absolutely use this if I lived in NYC; I'll recommend it to my friends there.

mhuffman

>This is a phenomenal application of how fine-based bounties can be used to rapidly improve compliance with the law.

This type of thing can get out of hand quickly. Without me giving controversial examples, just imagine for yourself the types of things that different states can make a crime, add a fine, then offer to give other citizens part or all of that fine if they turn in others. After that, think of how unscrupulous businesses could use it against competition.

hiAndrewQuinn

Compliance with the law is a separate issue from the contents of the law. If switching to a fine-based bounty system like this suddenly causes an uproar over a given law, then I submit the proper thing is to look over that law and perhaps tear it down. Any "law" that people put up with because it isn't enforced 9 times out of 10 is little more than a tax upon those too honest to get away with it.

As for businesses using it against one another in competition: Same deal, I think that's an excellent thing. If this idling law causes NYC businesses to shift en masse to faster loading and unloading practices because their competitors are watching them like hawks, I don't think that's a bad thing.

mhuffman

>Compliance with the law is a separate issue from the contents of the law.

Agree. More of my thought is what happens when everyone is incentivized with money to spy on everyone else? How can you misuse this as a government? How can unscrupulous businesses misuse this?

>If switching to a fine-based bounty system like this suddenly causes an uproar over a given law, then I submit the proper thing is to look over that law and perhaps tear it down.

I would submit that there is the danger that people might want to keep a bad law if they continue to make money by snitching. In fact, money is the exact wrong incentive for this sort of thing.

>Any "law" that people put up with because it isn't enforced 9 times out of 10 is little more than a tax upon those too honest to get away with it.

Think a little harder and see if you can imagine why a law that isn't strongly enforced still might exist.

sghiassy

Love the app; will use.

Scared of MAGA targeting brown people with this type of social enforcement

CamperBob2

Compliance with the law is a separate issue from the contents of the law.

Not really. If perfect, ubiquitious enforcement were possible, our laws would probably look very different.

renewiltord

Yeah, like the ADA for example. We should not have started down that slippery slope. Repeal the ADA!

ffsm8

I wish it was was more common around the world. Not just with parking though, but everything in the context of cars.

Like letting the police install a permanent speed trap on your property or even pay for the privilege of them doing so. I'd bet that'd curb a lot of speeding in short order

hiAndrewQuinn

There's no need for violence. In fact, the capital outlay would be inefficient.

If you want to curb speeding, the solution looks much the same: Pay reporters some portion of the fines collected from the speeder. You will very quickly see a cottage industry of Internet connected dashcams and on-board AI solutions spring up, because it's practically free money if you drive safely yourself for long enough. Pretty soon nobody will be speeding, simply because you never know who or what is watching.

This is a set of economic-legal policies I've been writing about here and there for a long time. It's great stuff.

gametorch

Sounds like the antithesis of freedom.

What a miserable society that would be to live in.

ffsm8

Uh, did someone advocate for violence?

pimlottc

“More Dunkin”? Is that an auto correct type for “more common”?

ffsm8

Oof, yes. I edited it

You created a subscription service for power-~~users~~ snitches?

This is wild demonstration of misaligned incentive structures at every level.

ryeats

Sounds similar to an HOA, let's just make a giant HOA for all of New York City.

screye

Amazing !

Decentralizing traffic enforcement is a win-win. Bravo to NYC for opening this sort of program and OP for turning it into an "efficient free market".

Will try it out soon. Bookmarked.

kennywinker

Fines not linked to income means it’s legal if you’re rich. I’m all for fining polluters to disincentivize pollution, but until we have income-pinned fines i’m not reporting any car under $50k

gametorch

It's not a win-win.

Look at China as a perfect example of what happens when you apply this idea at scale.

mstaoru

I lived in China for many many years and this is not a good example. Parking, and driving in general, is chaotic and unregulated. Yes, you have cameras everywhere that detect running on red or taking a wrong lane, but that's about makes it. Speeding, haphazard parking, everything is allowed. Scooters go anywhere. Bikes go anywhere. People go anywhere. Red, green, anything in between, it's a free for all. Like a policeman smoking under "no smoking" signs is totally normal. I'd say, you can get away with mostly anything in China, nobody would care (unless you're non-Chinese, then dutiful neighbors will report your every sneeze).

PS: Yet I do find OP's idea reminding me of China. Having a society that polices itself (just in China it's more about thought, not behavior) is definitely not a thing I would enjoy.

Zenbit_UX

I’ll never understand how people believe bike and pedestrian “infractions” to be the same as that of motor vehicles.

Members of this “get off my sidewalk!” group often fail to realize this: Did you study to become a pedestrian? Did you go to a bicycle driving school to acquire a permit to operate one? Was an exam at all given in order to use public foot or bike paths?

If the answer is no, then you aren’t held to the same standards as cars, which are heavily regulated and require licenses to operate.

Obeying road signs for bicycle and pedestrians are suggestions, rarely enforced, and the worst case scenario is usually you hurt yourself. Your ability to hurt others has an upper bound that society deems acceptable.

dale_huevo

> Decentralizing traffic enforcement is a win-win

Win-win for who exactly? Maybe we need to decentralize and AI-accelerate construction permit reporting too. Your backyard fence looks DIY and not up to code and your porch light looks like a fire hazard.

perihelions

They're trialing something like that in France. There's a project that uses machine learning on aerial photography databases to search for objects in peoples' backyards, for enforcement,

https://www.theverge.com/2022/8/30/23328442/france-ai-swimmi... ("French government uses AI to spot undeclared swimming pools — and tax them / The government used machine learning to scan aerial photos of properties")

organsnyder

Most cities have ways for neighbors to report things like this.

dale_huevo

Yes, and they're almost exclusively used by the worst type of vindictive chickenshit humans imaginable. I've known people affected by this, whose evil neighbors used 311 as a weapon because they simply didn't like them, and caused them tens of thousands of dollars in forced unnecessary renovations not to mention stress, for trivial violations that are widely ignored.

jen20

> Win-win for who exactly?

Society at large? All the people who don't have the breathe the fumes of some garbage commercial vehicle.

> Your backyard fence looks DIY

Provided it's up for code, whether it was "done yourself" or not doesn't matter.

> your porch light looks like a fire hazard.

Absolutely this should be reported.

gametorch

It's not a win-win for society.

What do you think of China, where the application of this idea is widespread?

pvg

We absolutely do that all the time?

vineyardmike

Within the last year or so, I discovered my city’s 311 app, which I’ve become addicted to. I don’t drive, so I’m always walking around the neighborhood, and got in the habit of always reporting graffiti, dumping, illegally parked cars, etc.

This had inspired me to try and make a few apps for civic use, but I discovered that many of the accessible web tools for my city have rules against bots. For example, the city maintains a list of locations and dates where parking is temporarily restricted for short term things like construction, but I can’t scrape it.

I really wish that the government (at any level) made more serviced and data available as APIs or digital formats. The government is usually bad at building/buying websites and services, and I’d have done it for free (or for $0.99 on the App Store).

yodsanklai

> always reporting graffiti

How does your city deal with graffitis? mine is plagued with graffitis and I can't see how they can be fought. It takes too much resources to remove them in a timely manner and impossible to catch the perpetrators.

vineyardmike

It’s just a game of cat and mouse. I dont think there is a way to “win”, because it’s so easy to make new graffiti, and not practical to try and police and catch people in the act. I think they require private property owners to clean their own graffiti, which really sucks, but makes it more manageable for the city to focus on public areas.

The city really just has a queue of cleanup sites and priorities locations that are high visibility or important, like school yards or transit infrastructure. An elementary school nearby had its mural destroyed by graffiti, and it was cleaned up within a day.

renewiltord

San Francisco does the sensible thing and fines the property owner. This is the just and right thing. In fact, I strongly support putting victims of drunk driving in jail: this strongly disincentivizes driving near drunk drivers.

dawnerd

They do that in my city too and it’s kinda insane. There was a shop that had a mural and the city considered it graffiti. So dumb.

dcsan

And the cost is often on the small business owner

In this age of generative AI, how would a someone defend against a maliciously AI generated/altered video report?

bob_theslob646

Most of NYC has cameras. The timestamp and location data from those can be linked.

You could also have multiple references to validate via crowdscoring.

You can also find people who are bad actors to decentivize them from mass reporting.

MathMonkeyMan

It seems the lawyers are making it difficult: https://www.nyc.gov/site/dep/environment/idling-citizens-air...

rafram

It used to be that as long as the vehicle was on the same block as a school or park, you only had to take a one-minute video (versus three-minute). Now there are some annoying documentation requirements if you want to submit a shorter video.

Doesn’t impact the overall usefulness of the program very much IMO — I just didn’t add special handling for school/park reports like I would’ve before they made that change.

michaelmrose

Presumably they don't want you taking videos of people who aren't in fact breaking the law and profiting from tickets. NYC regulation requires you to not idle more than 5 minutes.

https://dec.ny.gov/environmental-protection/air-quality/cont...

Although they don't require you to actually take a 5 minute video it is overwhelmingly likely that most people don't pull out there phone every time a vehicle stops in NYC so that most 3 minute videos are liable to be of 5 minute idles.

There are obviously 2 types of problem children cheaters and dummies. It's easier for cheaters to take a 1 minute video since even those who don't intend to idle for any substantial time may pause a moment. For dummies making them actually sit there and film 3 minutes decreases the chance that they will accidentally misunderstand how much time has passed. People are heavily biased towards their own benefits and are liable to miss-perceive 4.5 minutes as 5. Less possible when he pulled out his phone at the 2+ minute mark and now has to wait 3 minutes to have enough.

gametorch

Good. Those lawyers are doing God's work.

kennywinker

If a crime’s punishment is a fine, that means it’s legal if you’re rich.

crusty

I'll have to hunt down a link to the piece but I swear I saw a video about a few people in NYC who muddy go around finding idling vehicles and piece together the fine bounties into full time equivalent work. This could really disrupt their industry.

matsemann

Man, I wish my city would make it possible to report drivers breaking the law. My big issue is cars parking in the cycle lanes. 1830 cars got fined for that in my city in total in 2024. Aka 5 a day. As a single cyclist I see more cars parked in cycle lanes every day on my commute than all those hundred officers give tickets to in total..

cosmic_cheese

What I’d like to see is hard separation of roads and bike lanes. As a cyclist, nothing but a line painted on the road makes me feel unsafe, as a driver it’s difficult to not get nervous when passing a cyclist in the lane, and culturally drivers are generally favored over cyclists which results in things like parking in bike lanes not being adequately enforced. All these things would be solved by bike lanes being fully independent from the road.

josephcsible

> What I’d like to see is hard separation of roads and bike lanes.

That's a great idea, as long as the hard separation goes both ways with bikes no longer being allowed in car lanes.

cosmic_cheese

Doable, but would probably require bike paths to be wider than they currently are and split into two lanes: one for road bikers and one for everybody else.

matsemann

Why? I don't get this "gotcha". Is there any actual rational reason for making such rules, or is it stemming from some annoyance from seeing cyclists in the road?

There already exists roads where cyclists can't be: Highways/motorways. If the problem is cyclists in the road, that solves itself by building better infrastructure. Where there's adequate cycling infrastructure, cyclists prefer to use it. Where there's lacking or none, one should of course be able to use the road. Otherwise it would be a de facto ban on cycling, which I'm sure was your point?
