The weird thing is there seems to be a discrepancy between these publicized figures of millions of miles of auto-pilot on the roads, and the general feeling you get when you turn on the system yourself. I've used it on a Model 3 and it at least feels horribly insecure, the lines used to show detection of the curbs are far from stable and jitters around often, maybe it's more safe than it seems, but the feeling is I would absolutely not put my life in the hands of such a system... just looking at all the YouTube videos of enthusiasts driving around the countryside with autopilot and it's like watching a game of Russian roulette. Suddenly the car starts driving along the other side of the road or veer off into a house.. I would categorize it as a glorified lane-assist system, in its current state.
