I guess I saw it differently - which is, in what world are parents handing over a motor vehicle to their children, and good lord are there going to be a billion+ restrictions/safeguards on what they can do with that vehicle if their parents are not present in it. Also - tracking when a vehicle leaves a polygon zone feels like a minor subset of the already more privacy invasive "Where is this vehicle" that presumably exists already.
