Tesla launched its Robotaxi service in San Antonio, Texas, on Monday while expanding the service area in Austin, just one week after introducing the service in Fort Worth.
San Antonio becomes the eighth city in Tesla’s Robotaxi network and the fifth in Texas, joining Austin, Dallas, Houston and Fort Worth. The service is also available in Miami, Orlando and Tampa in Florida. According to EV, citing Sawyer Merritt, the San Antonio operating zone spans roughly 275 square miles, making it the company’s largest Robotaxi service area at launch, although Tesla has not officially disclosed the figure.
At the same time, Tesla announced an expanded Robotaxi coverage area in Austin, publishing a map showing the previous and updated geofenced zones. The expansion added 171 square miles, increasing Austin’s service area by 63% to 443 square miles from 272. As a result, Austin once again became Tesla’s largest Robotaxi service area overall, while San Antonio remains the company’s largest launch-day service area.
Tesla launched its Austin Robotaxi service in June 2025 with safety monitors onboard before transitioning to fully driverless operations in January. Like its earlier rollouts, the service initially operated with a limited fleet in a restricted service area. The company has not disclosed how many vehicles have been deployed in San Antonio.
According to the Robotaxi Tracker platform, Austin has more than 400 registered autonomous Tesla vehicles, while fleets in other cities range from a few vehicles to several dozen, including 24 in Fort Worth and five in Miami. Across Texas, Tesla’s registered Robotaxi fleet surpassed 1,000 vehicles in late October, comprising 544 Cybercabs and 507 Model Ys listed on the state’s autonomous vehicle registry. However, registry figures exceed the number of vehicles currently available to riders in active service.
Tesla did not disclose additional details about the service, including its operating hours, fleet composition, or whether vehicles would be equipped with onboard safety monitors. The company also did not confirm whether the service would use the Cybercab, the modified Model Y, or a combination of both. However, based on Tesla’s previous Robotaxi rollouts, the service is expected to begin with a limited fleet operating within a restricted coverage area before expanding gradually over time.
