Tesla expanded its Robotaxi geofence in Houston on October 26, growing the driverless service area from roughly 25 square miles to approximately 254 square miles, a tenfold increase2,3. The zone now covers about 1.2 million residents and is roughly five times larger than Waymo's 49-square-mile Houston zone.
The expanded boundary stretches from the original northwest pocket near Jersey Village southeast through central Houston, reaching parts of Bellaire, the Heights, Montrose, Midtown, downtown Houston and East Downtown5. The northeast portion of the 610 Loop remains outside the service area, and neither of Houston's major airports, George Bush Intercontinental or William P. Hobby, is included1.
Six months at a standstill, then a leap
Tesla launched unsupervised Robotaxi rides in Houston and Dallas on April 18, 2026, adding both cities to its existing Austin operations6,7. Houston's geofence had barely changed in the five months since, staying at roughly 21–25 square miles centered on Jersey Village and Willowbrook while Austin and Dallas saw repeated expansions8.
The Houston fleet currently consists of driverless Model Y vehicles with no in-vehicle safety supervisor. No Cybercab units have joined the Houston fleet yet. Electrek, citing Robotaxi Tracker, counted only 34 driverless Model Ys to cover the enlarged zone.
A crowded autonomous map
Houston now hosts at least three autonomous vehicle operators: Tesla, Waymo, and Amazon's Zoox, the last of which is still testing and not open to public hailing. A planned Uber-Nuro-Lucid robotaxi service targeting Houston in mid-2027 would add a fourth entrant. Tesla also operates Robotaxi service in Austin and Dallas, with San Antonio listed as a future market.
The expansion's rocket-shaped map drew attention online. Tesla's official Robotaxi account posted the boundary with the caption "Houston, we have liftoff". Elon Musk responded on X: "I swear it's just a coincidence". Multiple outlets noted the shape echoes a phallic Austin geofence map Tesla posted in 2025.
ANALYSIS Stretching the geofence tenfold with a fleet Electrek pegs at 34 vehicles means vehicle density per square mile drops sharply, raising questions about wait times and ride availability across the enlarged zone. Tesla's recent pattern in Texas favors geographic reach over fleet density.
