Agreed. They are deliberately taking advantage of the fact that people don’t understand how autopilot is actually used in aircraft.
Sure, the most pedantic of us will point out that, with autopilot enabled, the pilot-flying is still in command of the aircraft and still responsible for the safe conduct of the flight. Pilots don’t** engage autopilot and then leave the cockpit unattended. They prepare for the next phase of flight, monitor their surroundings, prepare for top-of-descent, and to stay mentally ahead of the rapid-fire events and requirements for a safe approach and landing. Good pilots let the autopilot free them up for other tasks, while always preparing for the very real possibility that the autopilot will malfunction in the most lethal way possible at the worst possible moment.
Do non-pilots understand that? No. The parent poster is absolutely correct: Tesla is taking advantage of peoples’ misunderstanding, and then hiding behind pedantic truth about what a real autopilot is actually for.
** Occasionally pilots do, and many times something goes horribly wrong unexpectedly and they die. Smart, responsible pilots don’t. Further, sometimes pilots fail to manage their autopilot correctly, or use it without understanding how it can behave when something goes wrong. (RIP to aviation Youtuber TNFlygirl who had a fatal accident six days ago, suspected to be due to mismanagement of an unfamiliar autopilot system.)
