I believe that no matter what Tesla tries to do, the term AUTO will draw up images of cars driving themselves and the term AUTOnomous and for the ley person they don't relate it to the aeronautical term. For clarity sake and to just avoid any future headaches, they should rename it to CO-PILOT which, in my opinion, denotes that they car is here to assist you but you are still the pilot. When full autonomous level 4 comes then they can change it back to autopilot.
