Tesla Robotaxi Launches in San Antonio, Its Eighth City

AUSTIN, Texas — Tesla has switched on its driverless Robotaxi service in San Antonio, making the Alamo City the eighth U.S. market where riders can hail an autonomous Tesla. The company announced the launch on its official Robotaxi account just after midnight local time, posting a map of the service area and a simple message: rides would begin at 5 a.m.

What stood out was the size of that map. Tesla rolled out San Antonio with a geofence of roughly 274 square miles, according to independent trackers — the largest day-one coverage area the company has ever posted for a new city. It is more than four times the footprint Waymo currently serves in San Antonio, and it reaches a wide swath of the metro from Loop 1604 in the north down to the area just south of downtown.

A Big Footprint From Day One

The initial zone covers close to one million residents, about 51% of the metro population, along with an estimated 721,000 jobs. For a first-day map, that is an unusually ambitious reach, and it signals how quickly Tesla has grown comfortable scaling its autonomy stack into new territory. San Antonio joins a roster that did not exist at the start of the year; Tesla began 2026 with zero unsupervised cities and now runs driverless rides in eight.

The San Antonio debut arrived on the same day Tesla widened its flagship Austin service area to roughly 443 square miles, an expansion of about 178 square miles since mid-September. Trackers log more than 450 unsupervised Tesla vehicles operating in Austin alone, underscoring how the fleet is thickening in its home market even as new cities come online. Riders curious about how the experience differs between vehicles can already see Tesla refining the details, including an app update that helps riders pick between a Cybercab and a Model Y.

Autonomy Momentum

The San Antonio launch fits a broader pattern of accelerating progress on Tesla's self-driving program, which has been clearing milestones at a steady clip — including fresh regulatory headway for city-streets Full Self-Driving in other markets. Each new city gives Tesla's neural networks more real-world miles, more edge cases, and more data to compound on, and the company has made clear that geographic expansion is central to its plan to turn autonomy into a recurring-revenue business.

Tesla has not said how many vehicles will initially serve the San Antonio zone, and coverage at the edges of any new map typically fills in over the following days and weeks as the fleet scales. The approach mirrors how Tesla has opened other cities: post an ambitious footprint, then deepen availability block by block.

What Comes Next

For San Antonio residents, the practical upshot is simple: a driverless Tesla is now an option for getting across much of the city, and the service area is already among the largest Tesla has launched anywhere. As Electrek detailed in its coverage of the rollout, the day-one map is the boldest Tesla has published to date.

With eight cities live and the Austin fleet still growing, Tesla's robotaxi network is expanding faster than many expected a year ago. If the San Antonio ramp follows the Austin playbook, riders should see coverage and car counts climb steadily in the weeks ahead — another step in Tesla's march toward a nationwide autonomous ride-hailing footprint.
