I think everyone is missing the key feature, which is that AP and NAP have to be turned on, and second, they turn off automatically when the driver does not touch the wheel, and they turn off when they reach pre-set limits, in the case of NAP, when it leaves a highway.
Smart Summon is limited in distance and requires the owner to continue to hold the button.
These structural limits mean that no Tesla car can operate "autonomously" - so it does not matter what you call it.
Its a distinction between a true self driving car which has a driver assigned to it but is actually designed to operate autonomously, and not only "designed" to operate that way, but in fact does operate that way.
Due to this discussion, I think this is the key. It does not matter how advanced the capabilities of the car may be, as long as the capabilities cannot operate autonomously they are not autonomous.
The key to regulators is safety, not semantics. As long as the features are safe when supervised, there is no reason to believe regulators will treat them any differently than the existing features.
Now everyone can drift off to the follow-up question, which is whether drivers concentrate more or less.
I frankly think that is what the difference between "feature complete" and actual "FSD" will be. You can have all the features of self-driving but as long as the car is checking every couple of minutes whether the driver is there its not self-driving. And its not self driving if the "self-driving" feature has to be turned on or automatically turns off.
