A Tesla Model Y with 'ROBOTAXI' scratched on its side was seen without a driver in Austin last week, followed by another vehicle described as a 'chase vehicle.'
Elon Musk implied that the lead car was part of Tesla's robotaxi fleet, set to debut soon after nine years since he first proposed the 'Tesla Network'.
Texas' autonomous vehicle regulations are lax, allowing almost anyone to obtain a permit by fulfilling basic administrative requirements and having insurance.
The state's AV-friendly environment is attributed to a hands-off approach and a law enacted in 2017 that encourages autonomous vehicle testing and operation.
