I don't know much about cars but I guess the point you're missing is that Tesla is the first (and only) company to market automated driving assistance as Autopilot. My first impression when I heard that first was that the car knew how to go from point A to point B with no or minimal manual intervention. With other cars it's marketed as what it is: driving tech that helps avoid accidents. But youtube is full of videos people letting go of the steering wheel on highways and stuff in Teslas.
