What Features Do You Want To See on Future Cars?

Heads up display (HUD) with at least vehicle speed. Got it on 2002 Grand Prix and love it. Changes between MPH and Km/Hr with the push of a switch.

I also think that cars that can parallel park themselves is a fabulous idea. Anyone that buys one of these cars because they, for whatever reason, can't parallel park a vehicle on their own should have their drivers license confiscated because ask yourself WHAT THE HELL ELSE CAN'T THEY DO BEHIND THE WHEEL OF THAT CAR???? IMO anyway.
