General Motors' autonomous vehicle unit, Cruise, has appointed former Microsoft and Amazon executive Marc Whitten as its new CEO. Whitten brings a wealth of experience from his time at Xbox and Sonos to his most recent role at Unity's Create. This appointment comes as Cruise is restarting testing of its autonomous vehicles following a pedestrian accident in San Francisco. The probe into the incident revealed cultural issues and poor leadership within the company, prompting several key leaders to depart. With the goal of creating technology that benefits society, GM CEO Mary Barra believes Whitten's leadership will be crucial for Cruise's success. The company is resuming operations in Phoenix, Houston, and Dallas, but remains under investigation in San Francisco. Whitten's appointment is part of GM's efforts to double revenue to $280 billion by the end of the decade. Other executive changes include Nick Mulholland and Craig Glidden joining Cruise in key roles.
