Uber and Rivian are partnering to deploy a large number of robotaxis, with reports suggesting up to 50,000 vehicles may be involved. The deal reportedly involves an investment of up to $1.25 billion by Uber in Rivian, with the robotaxis to be based on Rivian's R2 SUV model. The timeline for the deployment is not uniformly reported, with some outlets citing 2030 and others 2031 as the target year.
