I want the car to be able to contact emergency services, but not to otherwise be able to use the cellular network. Is there a good way to sabotage the eSIM, without otherwise breaking the modem? (This would still allow the car to be tracked via IMEI, but I'm not too worried about that: anyone capable of that is also capable of tracking my actual phone, and anyone buying that data will already know what car I own.)
There's often been a few cases of "disappeared" people who went missing and it turns out they actually crashed off the road somewhere and weren't found for a week or two.
That's extreme of course but there are probably a lot of accidents that happen in low-density rural country areas or late at night when there aren't many people around. The automatic e-call from the car gives exact GPS coordinates and severity of the accident, even if you are unconscious or if your phone that was neatly in the cup holder before the crash was flung somewhere else (potentially even flew out of the car etc) and you're trying to find it while someone might be dying in the seat next to you etc.
People didn't survive before all this. It's a mandatory feature now because it's so effective at saving lives. 2 to 10% reduction in fatalities and serious injuries apparently. Would you also question why we have mandatory airbags and traction control?!
right, but airbags, seatbelts, etc. are not internet connected. That's the critical distinction. I do not want the risks that come with my car connecting to the internet.
A much more reasonable ask would be for your car's systems to use your phone to place a call to emergency services. I absolutely do not want yet another internet connected device in my life, especially one like a car, where examples exist of hackers being able to disable the electronics remotely.
Funnily enough, I mostly hear about it from hyper-individualistic types. It's probably a facet of some American conservative-traditionalist belief cluster invented in the last 40 years, but it's hard to say for sure, because the people who say this tend to be bad at introspection, so can't answer my questions about it (even when they're curiously cooperating with my investigation).
