My personal solution: I won't own a car that has this sort of capability in the first place, and when I rent a car, I will never allow it and my phone to talk to each other for any reason.
If we can keep cars from the 40s running, keeping cars from the early 00s running is no big deal. Honestly older fully mechanical/analog cars with manual transmissions are often cheaper and easier to maintain than modern ones with high complexity and DRM on every part.
Sadly my desire for privacy will likely prevent me from ever buying electric unless I build my own car, which I might.
Me too. I'm not that sad about it, though. Saving an older car from being scrapped also brings environmental benefits.
So now I own a brand-new Chevy Bolt. You just yank a single fuse and that takes out OnStar and nothing else.
Absolutely. I don't buy cars that were made relatively recently.
