A new Texas law forced both companies to register their fleets. Tesla self-certified its cars as Level 4 despite previously telling regulators they were Level 2.

Tesla has registered 42 automated vehicles in its driverless Robotaxi service in Texas, putting it far behind Waymo in the state.

A new law and AV tracker tool gives the clearest accounting yet of how many robotaxis and self-driving trucks are in Texas.

In January, Tesla said that some of its robotaxis in Austin have begun operating without a human chaperone.
