Earlier this year, Cruise took over the former headquarters of Dropbox and announced plans to double its headcount in 2019.“Developing and deploying self-driving vehicles at massive scale is the engineering challenge of our generation,” Ammann said in a statement. “Having deep resources to draw on as we pursue our mission is a critical competitive advantage.”Cruise is in a race with Alphabet's Waymo to bring automated rail-hailing services to customers. Ford's ArgoAI is also chasing that goal, with a recent investment from Volkswagen, and Tesla has declared that it will have a million robotaxis on the road by 2020.However, Cruise's valuation is more specific than any of its competitors, and the company benefits from being part of the largest US automaker. San Francisco-based Cruise has been testing autonomous Chevy Bolt electric vehicles, with the goal of rolling out a commercial ride-hailing service this year.
