I understand your point, but I disagree. There are currently no cars that are considered fully self-driving as defined by the people who created them. Except for the ones that are really just remotely driven, they all come with warnings that a human the driver must be at the controls and paying attention.
Current self-driving cars are like a printer that works most of the time, but requires a human to read everything it produces and to occasionally write in a few things that it missed or got wrong.
It is mostly semantics. I answered the way I did primarily because I was responding to “There are already self-driving cars, aren’t there?”. That seemed to be asking about functionality, not naming conventions.
