Tesla Starts San Antonio Robotaxi: 8th Unsupervised, About 275 Sq Mi

Tesla’s Robotaxi network has expanded to San Antonio. The company’s official Robotaxi account announced the addition on X shortly after midnight, with unsupervised rides beginning November 9 at 5 a.m. CT.

It’s the second new Robotaxi city in as many weeks, following Fort Worth, where unsupervised rides started on November 2.

Tesla’s Biggest Robotaxi Launch Yet

San Antonio’s service area spans roughly 275 square miles, making it Tesla’s largest Robotaxi region at launch. It’s slightly larger than Austin’s 272 square miles, which has been growing since rides began there in June 2025.

Advertised sizes of Tesla’s unsupervised Robotaxi markets:

• San Antonio: Approx. 275 sq. miles
• Austin: 272 sq. miles
• Houston: 254 sq. miles
• Fort Worth: 143 sq. miles
• Dallas: 81 sq. miles
• Miami: 31 sq. miles
• Orlando: 26 sq. miles
• Tampa: 24 sq. miles

The San Antonio zone includes all of Downtown and nearly everything inside Loop 410, then extends well beyond it in most directions. Northward, it reaches Loop 1604 between I-10 and US-281, with a small extension up I-10 beyond 1604. It also extends west past State Highway 151, east beyond I-35, and south below I-410 toward I-37.

With San Antonio added, Tesla now offers unsupervised rides in eight cities, with service areas covering about 4.2 million people combined. A separate guide lists every market, including the supervised Bay Area zone.

However, advertised sizes are not the whole story. An analysis found Tesla’s actual pickup and drop-off zones in Texas are 22–41% smaller than advertised, though they still cover most residents. The map creator may test San Antonio next.

Right on Schedule

Fort Worth was unexpected, as it hadn’t appeared on Tesla’s previously shared lists of upcoming Robotaxi cities. San Antonio had been named. During its Q3 earnings call last month, Tesla identified Las Vegas, Phoenix, Jacksonville, and San Antonio as its next Robotaxi markets. After Fort Worth, more launches seemed likely, and San Antonio followed a week later.

Tesla has also been refining service in existing markets, recently extending Robotaxi hours in Austin and adding Calm Mode, which hides distracting visuals on the touchscreen for a more relaxing ride.

Cybercab Comes Next

San Antonio launches with Model Y robotaxis, while Tesla’s Cybercab program is expanding as well. The company already has more than 300 Cybercabs operating in Austin, and Cybercab rides are scheduled to begin in Dallas this month, its first market outside Austin.

With two new cities in two weeks and Las Vegas, Phoenix, and Jacksonville still on deck, another Robotaxi rollout next week would not be surprising.
