Sure you might not be able to legally claim that a Tesla is totally "autonomous," but the fact of the matter (to me, at least) is that they are putting in way more effort to solve the problem than legacy auto manufacturers are.
I can step into a Tesla today, press a destination, and go there without touching the wheel or pedals. Sure it won't be flawless but the fact is, I can. I can't do the same in any other consumer car, and the closest thing is a Waymo. The effort is there, I think its just a matter of time before we start seeing the legal stuff play out.
