Re: > at some point she was in the headlights,
*If* we take the video on trust, then the car was being driven with dipped headlights which made it difficult for the human driver to spot the pedestrian.
Don't take the video on trust, it gives a wholly misleading impression of the lighting conditions.
See here for a more realistic view:
Using dipped headlights was entirely appropriate in the circumstances: the area where the accident happened is well lit with street lights and the human driver would have been able to see the pedestrian for at least 400 yards, probably more.
