Uber shuts down self-driving operation in Arizona after fatal crash

Uber is to shut down its self-driving car programme in Arizona after one of its cars killed a pedestrian there in March. The company will focus its research efforts on Pittsburgh, where a number of AI car projects, including Ford's Argo AI program and Google's Waymo, are centred. Uber will also continue to test in San Francisco, where the company has its headquarters. In an internal email, the Uber executive Eric Meyhofer wrote that the company would be changing the way it tested its driverless cars. "When we get back on the road, we intend to drive in a much more limited way to test specific use cases," he said.
