I have said, and will continue to say, that the greatest sin of Tesla is that using autopilot requires good judgement from the drivers, and that is an unreasonable expectation.
To the layman, autopilot and self-driving are synonymous (as epitomised by this scene from The Darwin Awards: https://youtu.be/PNF7Ru1mMeo)
Aircraft don't often cluster together meters apart and travel in the same directions. If they did, Autopilot would certainly be used differently. This is why I think it is irresponsible to use the term for automobiles.
