One avid consumer really questioned the privacy and security of the new car computer systems such as OnStar when he went to purchase one.

If the company and the police can unlock you doors, blink your lights, honk the horn, start the engine, track you location, etc...imagine what a hacker or technically inclined thief could do?

His fears of an Orwellian future where everyone know what everyone else is doing could be coming true as evidenced by recent court cases and other examples.
