Well, the cars all have modems and quite a lot of processing. They don’t need to send a lot of data anywhere to check if it has seen familiar faces.
Modern cars are literally cameras with wheels.
I will admit that changing the settings on the safety tech changes nothing in this regard.
So you are sure that no one can access the cameras used for that?
