The problem with this isn't the idea of a car repossessing itself per se, because repossession is already a legitimate thing; it's the idea that your car can be remotely controlled by anyone other than you. There are already so many things that can go wrong. I don't want to buy a car that can be remotely disabled because I drove near a protest, or because there was a "clerical error" at Ford, or because my payment didn't go through, or because of a spotty connection or a software bug or a hacker! I'm also not sure I want to drive a car that collects and uploads analytics to my insurance company. (Although maybe it would be interesting as an opt-in system with a hardware kill switch that saves you boatloads of money if you don't drive like an a-hole...)
I'm pretty happy with the old, non-Internet-connected car that I drive. My phone already has all the smarts that my car needs for navigation and playing media and stuff. And from backup cameras to safer lane changing to full self driving, I can't think of a feature that I'd want to be built into the car and Internet-connected except for remote start (not sure I'd use it) or full-on "tell my car to drive somewhere without me."
