The term is certainly no exaggeration if you look at what an autopilot does in a plane. Keep attitude, maybe turn to next waypoint. All in all super primitive to what a Tesla does.
My bet is it will quickly fall apart. Ask your average person what "autopilot" implies and they're going to give you the sci-fi definition of a completely autonomous driving system, not many people know about the mechanics and limitations of autopilots in airplanes.
