Waymo’s robotaxis have disappeared from Uber’s ride-hail app in Phoenix, Arizona, bringing an end to their nearly three-year partnership. The change was confirmed by both companies to TechCrunch, with Uber preparing for a new autonomous vehicle collaboration and Waymo reintegrating its vehicles into its own fleet.

The partnership in Phoenix is now just a memory, replaced by the company’s latest van model, the Ojai, on the road. This development comes as both companies are gearing up to compete directly against each other in London this year. Despite the end of their collaboration, Waymo and Uber both see the Phoenix pilot as a success.

Waymo’s fleet has expanded significantly since 2023, now including around 4,000 vehicles, while Uber has made deals with numerous autonomous vehicle partners. The partnership in Phoenix was unique, being the only city where Waymo operated through Uber directly, and it now faces competition from new cities as Waymo plans to launch operations in about 20 more this year.

The robotaxi landscape has changed dramatically since the initial announcement of this collaboration. As AI looks back, it’s evident that the technology and its players have evolved considerably over these three years, marking a significant shift in how autonomous vehicles are perceived and implemented.
