Same happenned with Autopilot: in aviation, it is a very precise thing
Who told you that? They lied. There are lots of different things in aviation, all called autopilot. We handle the distinction by breaking autopilot devices down into classes, which are defined by capability. In fact, "autopilot" means many different things, from a simple system that can only maintain a heading to complex systems (and when I say "complex", I don't mean supercomputers, only as opposed to a function you can implement with discrete analog components, as the oldest autopilots did.
The autopilot systems on the newest commercial jets are capable of handling landings unassisted, at least, if everything is working. This is just not that hard a job any more. An Arduino with MultiWii (GPL'd) is enough to take a plane off from a field, fly waypoints and take pictures or drop bombs or what have you and then return to home and land again. And that's without any beacon signal from the ground. So clearly, the word "autopilot" covers a lot of ground.
Elon should have called it "Ship's Commander mode" (as the one which gives orders instead of holding the wheel) sound both mor awesome and a little bit less passive role for the driver.
Do you know what you call a simple computer on a boat which maintains your heading, and does nothing else? Yep, you guessed it, that's an autopilot.
The truth is that you cannot get autopilot even activated without a safety lecture, and if you willfully ignore the admonitions of the creators and then turn on a feature that is dangerous both to you and others if you misuse it, you deserve to die in a fireball and the only tragedy is that you may take others with you.
