Your argument fails as the analogy of car drivers with airplane pilots fails on various grounds.
a. The airplanes, which provides autopilot facility, their pilots have to undergo more rigorous and stringent training than what a ordinary car driver has to undergo
b. for different types of airplane autopilot systems the pilots have to undergo different types of trainings (you have not mentioned what kind of autopilot you have used, but I'd doubt if your autopilot training on one type of plane will automatically certify you to drive all kinds of auto-pilot planes out there, even within the same airplane category)
c. what Tesla is doing is on one hand it is saying (in fact, screaming in its adverts) that "we are bringing autopilot in cars", "we are bringing autopilot in cars" but when it actually is bringing just a driver assistance system and when that causes accidents, Tesla is putting blame on the customers for not understanding what is autopilot. This is not fair, as Tesla does NOT put any requirement for more rigorous and stringent training for its drivers the way airplane manufacturers/airliners put. So, Tesla is playing with the lives of not only its drivers but also of the other road users.
You are welcome to counter-argue my points. But this too much hoohaa about auto-pilot by Tesla and the subsequent bad publicity it is going to bring them is not good for them. People will not be subtle then because Tesla is not being subtle in their adverts now.
