Tesla Robotaxi Launches in San Antonio Across 274 Square Miles, Its Largest Day-One Zone

Tesla's Robotaxi service launched in San Antonio on November 9, 2026, with driverless rides starting at 5 AM local time (4 AM Arizona time) across about 274 square miles, the largest area Tesla has opened on a city's first day. Tesla's Robotaxi account announced the launch on X at 11:27 PM Arizona time the night before. Riders in San Antonio can now hail a Model Y with nobody in the driver's seat, and Tesla shareholders can count a second new Robotaxi city in a week.

The network added 2 cities in the first 9 days of November. Tesla's Q2 2026 update, published July 22, listed 6 metro areas with unsupervised customer rides: Austin, Dallas, Houston, Miami, Orlando, and Tampa. Our Robotaxi dashboard charts that count from Tesla's quarterly reports. Fort Worth joined on November 2, and San Antonio makes 8 cities, 5 of them in Texas.

Where the San Antonio cars can go

The San Antonio zone covers downtown and nearly everything inside Loop 410, and it reaches north to Loop 1604 between Interstate 10 and US 281, according to Not a Tesla App's map of the geofence, the boundary the cars are allowed to drive inside. It also stretches west past State Highway 151 and east past Interstate 35. San Antonio International Airport is inside the boundary, but Tesla is not offering pickups or drop-offs there yet, Teslarati reports.

Riders sign in to the Tesla Robotaxi app with a Tesla account and request a pickup inside the zone, News 4 San Antonio reports. Tracking sites counted about 7 Tesla Robotaxis in the city on launch day, the same report says, and Tesla has not published a fleet number for San Antonio. Waymo also runs driverless rides in the city, in a smaller area that covers parts of downtown and the airport.

What it means for riders and shareholders

The San Antonio fleet uses modified Model Y SUVs, the car the Model Y explainer covers. The two-seat Cybercab, which joined the Austin fleet on September 3, still runs mainly in Austin, and Tesla plans to wind down Cybertruck production in Texas to build more of them. Tesla's Q3 2026 update says the Robotaxi service reached nearly 2 million cumulative unsupervised miles by the end of September, and every new city adds roads and riders to that total.

For shareholders, each city is another market where a Tesla earns a fare on every ride instead of one payment at the sale, the model the Robotaxi explainer lays out. The Q2 update also listed preparations underway in Phoenix and Las Vegas, the next cities on Tesla's own list.
