Tesla Launches Largest Robotaxi Region Yet in San Antonio

Tesla has expanded its unsupervised Robotaxi network to San Antonio, marking the second new city launch in two weeks and establishing the company's largest service area at launch to date.

What Happened

Tesla’s official Robotaxi account announced the expansion on X just after midnight, with unsupervised rides beginning at 5 a.m. CT on November 9. The San Antonio service area covers roughly 275 square miles, making it larger than the 272-square-mile Austin market, which has been operating since June 2025. The zone encompasses all of Downtown San Antonio and nearly everything inside Loop 410, extending north to Loop 1604 between I-10 and US-281, west past State Highway 151, east beyond I-35, and south toward I-37. This launch follows the introduction of unsupervised rides in Fort Worth on November 2, a city that was not on Tesla's previously shared list of upcoming markets.

Why It Matters

With the addition of San Antonio, Tesla now offers unsupervised rides in eight cities, covering a combined population of approximately 4.2 million people. The launch aligns with commitments made during Tesla’s Q3 earnings call, where the company identified Las Vegas, Phoenix, Jacksonville, and San Antonio as its next target markets. However, advertised service areas may not reflect the full operational reality; a recent analysis indicated that Tesla’s actual pickup and drop-off zones in Texas are 22–41% smaller than advertised, though they still cover most residents. The expansion also coincides with broader fleet developments, including over 300 Cybercabs currently running in Austin and planned Cybercab launches in Dallas later this month.

The Bottom Line

Tesla has successfully deployed its largest Robotaxi zone to date in San Antonio, fulfilling a prior roadmap commitment. The company continues to scale its autonomous ride-hailing services across Texas, with further expansions in Las Vegas, Phoenix, and Jacksonville expected to follow.
