Who could possibly imagine something called Autopilot wouldn't require you to be in full control of car at all times?
That is far enough back to not have any relevance to Tesla's current customer demographic though.
This is not true for Tesla's FSD. Not by a longshot.
Autopilot can disengage and return control to the pilot at any moment. Pilots have to be on alert at all time. This has resulted in sone catastrophic outcomes, such as AF447.
