Uber is becoming increasingly prominent in the field of autonomous vehicles, following the sale of its in-house autonomous vehicle development unit in 2020. The company has partnered with dozens of autonomous vehicle technology companies across delivery, drones, trucking, and robotaxis. In a recent deal, Uber will invest $300 million in Rivian and will buy 10,000 fully autonomous R2 robotaxis ahead of a planned rollout in San Francisco and Miami in 2028, with the option to buy up to 40,000 more starting in 2030. This fleet will be exclusively available on Uber’s network. However, the risk ratio is heavily weighted towards Rivian, as it hasn't started producing the R2 SUV yet or deployed a self-driving system designed for robotaxis yet.
