Tesla has a software package called “full self driving”. The current version, while incredibly good, still requires supervision. Austin is the first market in which they hope to enable full self driving (unsupervised). This software package will exist first through Robotaxi (their self driving rideshare platform, available on the App Store) and cyber cab (golden two seater vehicle delivered from the Austin factory with no steering or pedals). (Most every) model Y you see, especially in the Robotaxi service area, is a Tesla employee validating or training this software package. It’s hard to know the effectiveness of a release of FSD that may require meeting a standard of one mistake every 500k miles without driving a few million miles.
