We do that every time we fly on a commercial jet. Landing, take off, on route are now mostly done by autopilot. Pilots' function are mainly monitoring anomalies. In the future I suspect autos will be similar.That's a good point but would you trust your life with a robot? Does a robot take everything going on into consideration or does it just do what it's programmed to do? When I see an idiot on the road that wants to pass me, I move over and let him pass, because I don't want that idiot following me. Tell me how a computer takes things like this into consideration? Even if I were old, I would be uncomfortable having a computer handle my life. There are already numerous reports of crashes from auto pilot drivers.
No thanks, I will use the small amount of energy and thinking it takes me to drive.
Think of machines as servants, not masters. Nowadays I use adaptive cruise control for stop and go LA traffic, less tiring when commute.
Take care.
