This page (https://www.tesla.com/support/full-self-driving-computer) says "Will help us enable a new level of autonomy with regulators approval"
And many many more for Elon Musk's Twitter and various appearances.
> *Will the FSD Computer make my car fully autonomous?*
> Not yet. All Tesla cars require active driver supervision and are not autonomous. With the FSD Computer, we expect to achieve a new level of autonomy as we gain billions of miles of experience using our features. The activation and use of these features are dependent on achieving reliability far in excess of human drivers, as well as regulatory approval, which may take longer in some jurisdictions.
That clearly states that there is still a technical challenge to overcome which is prior to any regulatory issues.
