If you're dumb enough to connect your phone to your vehicle, you deserve to get spied on.
Yeah, the fact that the auto makers were accused of intecepting text messages and their defense was "that's not illegal" instead of "OMG, no, we don't read customers' text messages!" is very telling about the amount of privacy you can expect in a modern vehicle.
Opt out. Buy an old clunker. If you're rich, buy an old muscle car instead.

This is not the future I was promised. You should be able to use your car and phone together without having to worry about this nonsense.
If your car has its own cell connection, it should not report back to anyone without informed consent. That doesn't mean forcing customers to agree to terms they never read in order to use the thing they bought.
I know there are a lot of open source options for IoT things, but sadly a motor vehicle is yet to be conquerored (apart from old vehicles).
I agree this isn't the future we were promised. But you nor I will change the auto industry.
