If these were esims they would be much harder to detect or remove?
BYD electric busses have recently rolled out where I live in Sweden.

It's not clear in the article how exactly they discovered it, but by the text that mentions it, I do get the impression they just came across the SIM ports/cards themselves:
> internal tests at a secure facility found Romanian SIM cards inside the buses
But it could also have been that they put the entire bus in a giant Faraday cage (or similar) and tried to see if it emits anything. If they did that, then eSIM or SIM wouldn't have matter, nor where on the bus it was, they'd eventually see it. But if they just physically came across it, then maybe eSIMs would allow them to place them in less accessible areas. But then maybe that wouldn't matter anyways, if the SIM cards are permanently attached anyways.
Bottom line, hopefully wouldn't have made a difference.

This is just stupid. All modern vehicles har been fully remote controllable for years.

The issue was the eSIMs identified were not disclosed by Yutong, which clearly falls afoul of procurement and cybersecurity regulations.

I wasn't aware of that, thanks. But still, if you go buy a car right now, I doubt they are going to make it a sales pitch that you are not the only one who can control your car.

This is why we invented the fine print.
Not putting this information in the fine print is fraudulent behaviour
Whatever happened with the Polish trains that had all the backdoors that were discovered?
