Tesla has officially started autonomous vehicle 'testing' phase in Austin, Texas ahead of its Robotaxi launch. Shortly after, Tesla's driverless Robotaxi was spotted in Austin with a manned trailing car. Tesla aims to 'tentatively' start Robotaxi service on June 22. The Robotaxi is an unmodified Model Y. Tesla claims vehicles produced since 2016 would be capable of unsupervised self-driving.
