Autopilot 1 was incredible. I drove about 720km that day, using a lot of AP. Although you have to keep overseeing that AP does not mess up, it helped me incredibly by reducing the amount of micromanaging, constant high alertness, stress, fatigue I would have normally encountered driving in European dense city and highway traffic. It really keeps the lane better than me already, giving me a much safer feeling driving for hours in dense traffic. Heavy commuter infused city-highways and traffic jams become a breeze. I cannot wait for my Model3 to arrive! Looking forward to a minimal emission, quiet, electric future with self driving cars.
