a dumb head unit that’s connects to either CarPlay or Android auto?

if the car is just a dumb display, they can’t collect any info.

on the flip side I don't use Android Auto because, well, I know who that's going to and who is listening. I have a BYD and use the in car display precisely because it's going to China who don't want to do me harm, it's my government that wants to do me harm if I attend a climate protest or despair at the situation in Palestine and articulate that, my government in those cases is looking to arrest me.

Id never buy a connected Euro or US car. Here in Australia there are quite a fee non connected Euro cars (BW and Cupra) as well as Toyota and Subaru and the biggest gripe from their customers is their lack of connected-ness.
