> Moreover all this effort in avoiding being tracked doesn't really mean much when all cars have a very visible and unique identifier that's mandated by law (ie. license plate).

I agree with the first half, but not this. The difference between people seeing your license plate and your car/phone/etc systematically recording and storing your exact position is the same as the difference between someone on the street seeing my face vs. a facial recognition camera identifying me and storing that data point forever. People don't memorize or care about your plates. The police could take note of them or even put it on some record, but the number of cops is so low (and the number of cops that would care about my license plates is even lower) that whatever scraps of data are recorded would probably be pretty useless - and besides, that data isn't sold off to private entities, at least where I am.
