Tesla and Elon Musk had hoped that the rollout of a long-awaited Robotaxi service in Austin, Texas, would mark a major step forward for the company, bringing fully autonomous driving technology to the public.

Musk and Tesla have no ability to judge and predict the progress of their system, so that makes it a challenge to judge them even by what they do

Shareholders said this included Musk's assurance on an April 22 conference call that Tesla was "laser-focused on bringing robotaxi to Austin in June," and Tesla's claim the same day that its approach to autonomous driving would deliver "scalable and safe deployment across diverse geographies and use cases."
