In March 2018, the death of Elaine Herzberg by an Uber self-driving vehicle in Tempe, Arizona resulted in temporary pause to Uber's self driving vehicle testing.  According to police, the woman was run down by the Uber vehicle while attempting to cross the street, while the person in the vehicle was watching videos on her phone.  Uber pulled its self-driving cars off all public roads and quickly reached a settlement with the victim's family.  There was disagreement among local authorities as to whether or not the car or the victim was at fault.  In December 2018, after receiving local approval, Uber restarted testing of its self driving cars, only during daylight hours and at slower speeds, in Pittsburgh and Toronto.  In March 2019, Uber was found not criminally liable by Yavapai County Attorney's Office for the death of Ms. Herzberg. The company changed its approach to self-driving vehicles after Herzberg’s death, inviting both Waymo and General Motors’ Cruise self-driving vehicle unit to operate vehicles on Uber’s ride-hailing network.
