Tesla announced today that its “Robotaxi” service is now rolling out in Dallas and Houston, marking the company’s first expansion beyond Austin and San Francisco. The company shared maps of the two new service areas, which appear to cover small slices of each city. The Houston geofence covers approximately 25 square miles, according to early user analysis of the maps, while the Dallas zone appears to center around the Highland Park area. For context, Tesla’s Austin geofence has grown to roughly 245 square miles after months of gradual expansion — but that took nearly a year to reach from an initial 20-square-mile footprint. Tesla’s official @robotaxi account on X posted the announcement with two map images showing the service boundaries, but provided no details on fleet size, whether rides will be supervised or unsupervised, or pricing. The post simply read: “Robotaxi now rolling out in Dallas & Houston.” What we know — and what’s missing The announcement is notably thin on specifics. Tesla did not disclose how many vehicles will operate in each city, whether those vehicles will have safety monitors inside (as the vast majority of its Austin fleet still does), or when the geofences might expand. As we reported in March, Tesla’s Austin operation still relies on only a handful of unsupervised vehicles — somewhere between 4 and 12 Model Ys operating without a human safety monitor — out of a total fleet of roughly 80 vehicles, though most of those are not operating at the same time. The remaining cars still carry safety monitors in the driver’s seat, and all vehicles are remotely supervised by Tesla staff. The company’s track record on “Robotaxi” promises provides reason for skepticism. Elon Musk predicted 1 million robotaxis on the road by 2020. He promised 500 vehicles in Austin and over
