Tesla's Robotaxi service in Houston just got a lot bigger on the map. On October 26 the company's Robotaxi account announced "Bigger service area now live" and posted a new boundary that runs from the original zone in northwest Harris County southeast through downtown to Bellaire.
From 25 Square Miles to About 254
When Tesla launched in Houston in April, the service covered roughly 25 square miles around Jersey Village, Willowbrook, and part of FM 1960. Tesla has not published the size of the new area. Robotaxi Tracker, an independent site that maps the service from rider data and sightings, puts it at about 254 square miles, roughly ten times the launch zone.
The outline drew attention for its shape, which several outlets compared to a SpaceX Starship rocket. That is a fun detail; the more useful one is that the zone now reaches the parts of the city where people actually work and go out.
The Fleet Is the Real Constraint
A bigger map does not mean more cars. Robotaxi Tracker counts about 34 driverless Model Ys in Houston, up from 22 three months earlier. Spread over 254 square miles, that is about one car for every seven or eight square miles, so wait times across most of the new area will depend on how fast Tesla adds vehicles. These counts are crowdsourced; Tesla does not publish its fleet size.
Where This Leaves Houston's Robotaxi Race
Waymo has offered fully driverless rides in Houston since February and roughly doubled its service area in May ahead of the World Cup, to nearly 50 square miles. On area alone, Tesla's new zone is now far larger. The two companies are taking different approaches: Waymo uses lidar-equipped vehicles and grows its map more slowly, while Tesla relies on cameras and has been expanding its maps faster than its fleets.
They are not the only ones. Zoox and the Uber–Nuro–Lucid partnership have also picked Houston, which we cover in our overview of the city's robotaxi players. The next measure worth watching is not square miles but how many cars each company runs, and how they handle Houston's weather: Waymo paused service after flooding incidents this spring.
