sometimes i don't mind the cross country trip, and even enjoy the drive, but autopilot on that thing would come in handy
cars can be redesigned for comfort -- couches facing inward, or towards more televisions. i'd imagine that some roads for a while will need human operators (the roads less traveled) but if even the interstates could be automated it would be a huge boon
yes, as it stands now, it's only new cars. however, there will come a point in the future where it will be illegal to have a car with only a human operator available to it, no doubt, but that's decades from now
