Personally, I still prefer Android Auto (i.e. phone projected onto car screen) to Android Automotive (Android built into the car infotainment system). My phone gets way more updates than my car, and it's cheaper to buy a new phone once it stops getting updates.
I have the same sentiment towards smart TVs vs plain old "dumb" TVs + a streamer.
Android Automotive (the car OS) does support phone projection (Android Auto and CarPlay).
From what I’ve seen in reviews of cars that have it, Automotive is pretty solid, and I’d take an EV that had it as long as CarPlay were an option. (So no GM for me).
They can’t gather data from my use of the built-in apps if I don’t use them.
