Earlier quoted context omitted.
I still won't even buy a car with GPS. Seems I'm in a vanishing minority. It won't pass, because people born after 1990 have spent their adult lives in a world with surveillance machines in their pockets at all times. Their cars are just big phones. By 2040 you probably won't even be allowed to drive your own vehicle.
GPS is a one-way communication. It's really no different from radio in that regard (a signal sent from far away and you have an antenna to read the signal). Unless there's also a cellular modem in your car (which pretty much every modern car has today so I'm not pretending this is unusual) it's impossible for others to monitor your location. You can simply disable the cellular modem and enjoy using GPS without anyone…
But I won't buy a car where those things are integrated and can't be turned off. Several people here seem to assume that I don't understand that almost all cars from the past decade have this capability.
It's one reason I drive a car from 1980, with basically no electronics whatsoever. (Other reasons being: it's more fun, it's simple to repair, and it will still run after an EMP).
