Uber plans to purchase 10,000 autonomous Rivian R2 robotaxis, with the option for 40,000 more by 2030. Initial deployments will start in San Francisco and Miami in 2028, expanding to 25 cities by 2031. Uber's CEO expressed confidence in Rivian's integrated approach to vehicle design and manufacturing. The investment of $300 million is contingent on meeting autonomous milestones by 2031. Rivian, based in Irvine, California, produces high-end vehicles and is working on a new facility in Georgia.
