Tesla state that autopilot will "match speed to traffic conditions, keep within a lane, automatically change lanes without requiring driver input, transition from one freeway to another, exit the freeway when your destination is near, self-park when near a parking spot and be summoned to and from your garage."
I believe the problem lies in "Enhanced" and "Full self driving hardware". While this is an important point and is probably true, there should probably be bigger warnings that there is currently no full self driving software, and therefore, no full self driving.
