You can somewhat opt out of auto surveillance by avoiding cars with:
-android auto
-apple carplay
-starlink
-cameras
-satellite radio
-onstar/similar
Generally, this means older year vehicles.
Discussion
In the US all vehicles after 2015 (i think) are required to have telematics tracking systems. You cannot opt-out of it. People with dealer access (I do) can often look at everything you do with a car, especially location, location history, nearby devices etc. These systems cannot be removed. Don't purchase new vehicles if you really care about this stuff. I just needed your VIN number to gain access to these tracking systems.
Covered this topic in a podcast a few months ago too!
