> Imagine if your car could only drive to locations approved as safe by the car manufacturer

We're not very far away from that. Example: Tesla sells auto insurance based on real-time tracking of driving behavior, and explicitly lists "where you live" as a factor. So it's quite possible "real-time location safety" is already part of their model. So you may already be charged more for driving to your Grandma's house. Granted this is not a ban, but it is close enough for discomfort and all it takes is the right (or wrong) motivation and the loop can be trivially closed.
