The goal: launch robotaxi services in at least 15 cities by the end of 2026 and scale to 28 cities by 2028. Uber has previously invested $300 million each in Lucid and Rivian, positioning both EV makers as potential suppliers for its autonomous fleet. The two companies are collaborating on a fleet of 100,000 autonomous vehicles expected to begin rolling out in 2027. By maintaining a human driver network alongside its autonomous fleet, Uber can guarantee coverage and reliability in situations where self-driving technology falls short. If autonomous vehicles are the future of transportation, and Uber can successfully integrate them into its existing network, no driver payouts on autonomous trips means Uber keeps a much larger share of each fare.
