Edit: Just asked because of curiosity. I’m not actually looking for such vehicles.
Edit 2: So for context, my parents new Toyota has this feature that allows the GPS location of the car to be sent to toyota, then you can see the location via an app on android/ios (it’s supposed to be an anti-theft feature). The data is sent via an antenna that connects to cell towers, which then connects to the internet, and to the toyota servers. “Diagnostic” and “maintenance” information is also sent via those same antennas.
The dealer said it could be turned off, but who knows if they are really off. There’s not a hard switch on the car.
Not OP, but cars are going down the same path as countless other “smart” devices. Things like fridges and TVs now include a considerable amount of tracking and datamining. It’s not unreasonable to expect that cars are doing the same thing, especially given that many include onboard cellular modems for the infotainment system.
