Google and other companies are working on self driving cars. They are predicting that driving a car will become a thing of the past. Personally I don't like the idea of self driving cars as it is surrendering freedom for a minor convenience. Also if the day should come to pass that all modern cars on the road are self driving, would old manual driven cars be banned since they would not be support by whatever control networks are used? Then there are concerns about criminal hacking of self driving car and even government abuse with overrides. Anyone else concerned about this?
