It's pretty clear to me (from the second half of the video) the driver was looking down at her phone and glancing up at the road periodically. IMO if she had been focusing on the road, she would have at least started braking before hitting the pedestrian. Or perhaps actually stopped before that happened.
My more generous interpretation is that they were looking at the computer screen where the car shows its interpretation of the situation, people tend to lift their phone towards their face.
This is only a fig-leaf of a driver (for catching legal flak by sitting in the front left seat), not actually operating the vehicle at all. This part was inevitable, given the unbounded technooptimism.
