I've driven a brand new Range Rover with the assist package, and that car was fully automatic in city and motorway driving for all intentions and purposes, as long as there was a car in front of you. You would engage the "smart" cruise control, and it would just follow the car in front of you perfectly, making turns, stopping and starting. I've driven it on the motorway at 80mph, then a car in front of us was taking an exit, I put the blinker on, the car followed, and drove around the bends following the car in front, until we came to a stop at a set of traffic lights. Then when the traffic started moving again, all I had to do was to tap the accelerator, and the car started following again. That was without me touching the steering wheel at all.
