The name "Autopilot" for their lane-keeping feature clearly relies on most people not knowing how autopilot works in planes, because it's heavily implied to be autonomous driving and it's not. It's just a Tesla scam.

THIS. If you asked a bunch of pilots about the capability level they'd expect from something called "autopilot", then compared with the answers you'd get from a bunch of Joe Averages...yeah. When people don't know squat, and they hear some Marketing-speak, and they'd like to believe - the next thing you know, they've convinced themselves that Santa's magic elves are making it all work, and nothing bad could ever possibly happen.

I don't think its clear they are relying on people not knowing how autopilot works on planes because I don't think most people know autopilot on planes exist for the most part. 10-15% of the US population has never been on a plane.

AFAIK pilots don't need to hold the yoke for autopilot to work on planes, but this is required in Tesla.
