Earlier quoted context omitted.
No. If you jump in front of a train, is the train driver's fault? Where is the pedestrian's responsibility?
In Arizona it is the driver's responsibility to yield to all pedestrians on the same side of the road. She somehow crossed 3 and a half lanes of traffic without the Uber SDV ever perceiving her. Their fault.

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.
