Authorities in Arizona have released dramatic dash cam footage showing the fateful moments leading up to a self-driving Uber car’s fatal collision with a pedestrian. The video released by Tempe police on Wednesday shows the car driving at what appears to be a reasonable speed along a relatively empty road Sunday night before it runs over a pedestrian. The clip stops just a split second before impact. The victim was later identified as Elaine Herzberg, 49. The video also appears to show that the safety driver, Rafaela Vasquez, was alert at the time of the accident but also repeatedly looking down at her lap in the build-up to the collision.
