In the short clip from the self-driving car's external camera, the victim, Elaine Herzberg, is shown walking across an unlit street with a bicycle, something previously reported by authorities. The internal camera footage, used to monitor the self-driving Uber's human safety operator, shows the driver looking at something off camera repeatedly. It's not until the last second where the driver, Rafaela Vasquez, looks up and reacts to the impending collision.

Police reports state that the Uber Volvo was traveling at a rate of 38 miles per hour in a 35-mph zone and was operating in self-driving mode. It's unclear at this time why the vehicle's sensor package failed to identify Ms. Herzberg as she crossed the street, let alone failed to brake in advance of the collision. It would appear that Ms. Herzberg was walking calmly into the street -- not darting, as has been speculated.
