I had the pleasure of driving a 7.0 Model S Auto Pilot this morning. It was impressive. Unlike some videos, I chose to lightly hold the steering wheel as the Model S held the road through the straight aways and curves. It was flawlessly moving with no effort from me. A press of the turn signal, and it changed lanes smoothly and safely. It was raining, which is usually "high-stress" driving. Rain causes more focus, but the Tesla was totally in control. It was a more relaxing drive than I normally experience. At the end, pulled up beside two other Model S's parked by the curb and wall. The Representative had me pull up beside the front car, the "P" emblem id'd the space and I released the brake, pressed the button on the display, and into the space the Tesla went flawlessly. The steering wheel spun, the brakes applied, the wheel spun again and it shifted forward. It was parked in a few seconds.
I wish I had this on my last 700 mile drive. It would be much more relaxing, knowing that if my focus lapsed, the car "had my back". Not needed for round the town, but certainly worth engaging on road trips.
