Uber Technologies Inc. will not be held criminally liable after one of its self-driving cars hit and killed an Arizona pedestrian last year. Prosecutors said in a letter made public Tuesday that there was "no basis for criminal liability" against Uber, but said the human driver, who was reportedly watching videos on her phone at the time, could still face charges. Investigators in Tempe, Ariz., previously concluded that if the driver had been paying attention to the road, the crash could have been avoided. The crash in March 2018 forced Uber to halt its self-driving program nationwide, though it resumed testing in Pittsburgh in December after reportedly making safety improvements.
