Waymo robotaxis can now be hailed in Atlanta via Uber. The two companies, which already offer the “Waymo on Uber” service in Austin, said the commercial service will initially cover about 65 square miles in Atlanta. The launch, if successful, is poised to propel the businesses of both companies. Uber, which has locked in partnerships with 18 autonomous vehicles companies, said it has an annual run rate of 1.5 million mobility and delivery AV trips on its network. Meanwhile, Waymo said it provides 250,000 paid robotaxi rides every week across Austin, Los Angeles, Phoenix, and San Francisco. The addition of Atlanta to that list should push those numbers up. Waymo’s fleet in Atlanta is in the “dozens” and will eventually be expanded over time. The companies have previously said the fleet shared between Atlanta and Austin will grow to the hundreds. The “Waymo on Uber” service is a hybrid of sorts where robotaxis and human-driven vehicles intermingle. Uber users can set their preferences in the app to increase the chances of being matched with a Waymo. That structure differs from the other markets where Waymo operates. In those cities, riders use the Waymo One app to hail robotaxis. The “Waymo on Uber” service splits the responsibilities of owning and operating a fleet of driverless vehicles. Uber handles the charging, maintenance, and cleaning of the autonomous vehicles, and manages access to the robotaxis via its app. Meanwhile, Waymo monitors the tech and the autonomous operations, including roadside assistance and certain aspects of rider support.
