The car was not in the right place, or it would not have hit her. In the state of Arizona a pedestrian has right of way in front of any vehicle, and the driver must yield to any pedestrian on the same side of the road.

Edited to add: We don't know anything about her physical or mental condition that might have made it difficult for her to perceive the car or the distance when she was crossing, so to assume that she had perfect perception and chose to cross in front anyway assumes facts not in evidence.

Coming back to this, I was wrong about the details of Arizona law. They require pedestrians to yield to drivers outside of crosswalks, marked or unmarked.

However, I still think Uber violated 28-794.1 and .3.

  Notwithstanding the provisions of this chapter every driver of a vehicle shall:
 
  1. Exercise due care to avoid colliding with any pedestrian on any roadway.
  2. Give warning by sounding the horn when necessary.
  3. Exercise proper precaution on observing a child or a confused or incapacitated person on a roadway.
