Thus, with no back-channel, simply disabling it is no problem and noone will know.

Indeed- I'd expect they'd have to have a big penalty for being caught with a modified car. Maybe a sort-it-out-in-a-few-days-or-else kinda thing.

Unless the car records the information and gives it to someone else, there isn't a privacy issue here to worry about. If they want to track you, they'll hide their own micro-GPS receiver + secret transmitter somewhere you won't look :)
