Agreed. Speed, particularly on sub 1 hour drives, is mostly about competitiveness. If you're no longer competing with other divers, because you have a robot that is, what will that extra 10mph do for you?
Particularly when you can work in your car. Or watch a movie in your car. Or have sex.
Why assume that the robots won't compete? Cars today are marketed based on their potential for speed. With that out of the picture, why shouldn't we expect manufacturers to compete to have the "fastest" autodrive systems?
I want this. A rollercoaster like experience on the autobahn, nice :D
