According to Reuters, police obtained records from the streaming service that shows that Vasquez was streaming The Voice the evening of the crash. The driver's phone streamed the show for 42 minutes, until approximately 9:59 PM, which is when the fatal accident occurred.
The internal vehicle video footage immediately surrounding the accident shows Vasquez looking down repeatedly before the collision. "The inward-facing video shows the vehicle operator glancing down toward the center of the vehicle several times before the crash," said the NTSB report on the accident, which was released in May. Vasquez insisted she was monitoring the vehicle's autonomous interface.
Uber's self-driving tests mandate that a driver must pay attention to the road at all times and drivers are prohibited from using mobile devices when the vehicles are on public roads. There were certainly other factors involved in this crash -- the road wasn't well lit and the pedestrian wasn't crossing at a crosswalk, not to mention issues with the pedestrian detection software, to start. But this isn't good news for Vasquez or Uber.
Since the collision, Uber has ceased its self-driving tests (though the company is planning on starting back up in Pittsburgh) and increased simulation testing. You can bet that, after this revelation, Uber will face some scrutiny over the drivers for its autonomous vehicles.
