I would also add; that I will stay consider these vehicles to be unsafe until the manufacturers can prove to be beyond a shadow of doubt that I or the local computer are the ones piloting the vehicle.
When a random person can remotely take control of a vehicle; whether it be the windshield wipers, or full control of the vehicle, then it is not safe to contain a power source in the vehicle near a public road. I don't want 4chan driving me into another vehicle.
