Although I don't have autopilot in my classic S85, I'm thinking that the next version of the cars should really have heads up displays. A flashing red light for collision warnings (we had this on our 2012 Ford Explorer -- it was just a red LED strip that would flash at the base of the windshield with an audible alarm in a collision warning) would be good to have. In addition, a nice HUD showing the current autopilot lane tracking lines, etc would be a very easy way for users to keep eyes forward, and not have to scan up and down to the instrument cluster to be sure the road ahead is what the car is actually tracking. I don't have real world experience but I'd imagine AP users are scanning up, down and around while in AP mode. This would make for a safer and more comfortable experience, I'm sure.
