Ok first of all Twisted, the police work for us, and the car would drive the police to us...unless by then socialism has set in, in which case we are all screwed anyway.
Seth, you won't have to buy a car, just press the button that say's 'car now'. So, not owning 3 cars (like I do) you will only pay for the time you have it. No monthly bills, no insurance, no maintenance.
Clarance, I doubt if you will have to have a background check to get in the car, there will have to be privacy settings. I mean otherwise, how will the 'ladies of the night' operate?
