It was deemed the pedestrian was also partially at fault. She was crossing a road, at night in a dimly lit portion of the road, no where near an intersection and with seemingly no regard of awareness of oncoming traffic in dark colored clothes which is the opposite of pedestrian safety for walking/running at night. If you watch the video, even a human probably wouldn't have hit the brakes in time with average reaction speeds, the person was only visible for 1.5 seconds before impact. I believe the term is contributory negligence, when both parties are making mistakes that lead to the accident.

Grounding the fleet would have saved her life, but its arguable any other driver could have hit her and only applied the brakes for a short period of time, not enough to stop or slow to a less lethal speed before impact.

You're watching a compressed to shit video of a cheap dashcam. Human eyes have literally thousandfold the dynamic range of the pinhole sensor in that thing.

Sorry, but this is a human life we are talking about here.
