As expected, Uber is selling off its self-driving unit. On Monday, the company confirmed the sale of its Advanced Technologies Group (ATG) to Aurora Innovation, one of its now previous competitors in the autonomous vehicle space. As part of the deal, Uber will invest $400 million in Aurora, with CEO Dara Khosrowshahi joining the startup’s board of directors. Effectively, Uber is paying Aurora to take the division off its hands. In the near term, the startup will put ATG’s expertise to use on a self-driving truck it’s working on. Robot taxis will come later, with Uber licensing the tech from Aurora.
