Exactly. Everything below L4 is _incredibly stressful_ and unpleasant to drive, because you have to be constantly aware and alert without having anything to do.
In the case of Tesla, daring to call such a system "Autopilot" is a breathtaking level of irresponsibility. You are responsible for the vehicle you are driving, practically, morally and legally, even if a companies' marketing and the system itself does its very best to divest you from that simple and obvious truth.
In that case, autopilot is the correct term.
Pilots still are required to be able to take over immediately for an autopilot system and are responsible and accountable for all those items you list and more.
Calling it autopilot is precisely what it is, calling it self driving would be false marketing.
