Tesla has just 42 unsupervised Robotaxis on the road in Texas. Alphabet’s Waymo has 577.

Forty-two is the answer to life, the universe, and everything in Douglas Adams’ classic “The Hitchhiker’s Guide to the Galaxy.” It’s also the number of unsupervised Robotaxis Tesla has on the road in Texas, the only state where it’s operating autonomous service, according to records from a newly required government database in the state.

That’s much lower than CEO Elon Musk had hoped, as the company struggles to ready its camera-only autonomous vehicles for commercial scale. In 2025, Musk said that the service would be available to “half the population of the US by the end of the year.”

Even smaller competition has more: Avride has 317 and Nuro has 47. Meanwhile, Tesla’s chief rival, Alphabet subsidiary Waymo, has 577 in operation in the state. Nationwide, Waymo’s fleet currently numbers more than 3,000.

Unfortunately for Tesla, figuring out how to actually scale its robotaxi fleet remains the ultimate question.
