EVwire brief: Tesla is bringing its Robotaxi service to San Antonio, Texas, with a launch geofence covering an estimated 275 square miles (712 square kilometers), the largest service area in Tesla's network.
Tesla's official Robotaxi account announced on X that rides in San Antonio will open at 5 a.m. local time on Tuesday, November 10. The launch map shows a service area centered on downtown San Antonio, reaching up to Loop 1604 in the north and extending past Loop 410 to the west, east and south (our read of the map).
Here's the launch map Tesla shared on X:

San Antonio brings Tesla's unsupervised Robotaxi service to eight US cities. Based on our read of Tesla’s Robotaxi geofence for San Antonio, it appears that the area will be largest-ever Robotaxi service area at launch, edging out Austin's 272-square-mile geofence and topping Houston's 254-square-mile zone.
It is also nearly twice the size of the 143-square-mile geofence Tesla opened in Fort Worth just a week ago. At its widest points, the San Antonio zone seems to run roughly 19 miles (31 km) both east to west and north to south.

Context:
San Antonio was one of four cities, along with Las Vegas, Phoenix and Jacksonville, that Tesla named as upcoming Robotaxi markets in its latest safety report. Its launch caps a run of fast geofence growth across Texas, with Tesla's Houston expansion in late October replacing a roughly 25-square-mile (65 km²) zone with one about ten times larger, and Austin's service area growing to its current size around the same time.
Tesla's Texas fleet and operating hours have been growing just as quickly. Vehicles registered to Tesla's Robotaxi service in Texas topped 1,000 units in late October. Austin rides now run from 5 a.m. to 2 a.m., or 21 hours a day, and Tesla said during its Q3 2026 earnings call that it is aiming to run Robotaxi around the clock by the end of 2026.
