Watched the video many times, still have to sympathize with driver more than pedestrian.
If you see carefully, the taxi and motorcycles in the middle line apparently spotted the xiao lang and slowed down already.
Does this mean the blue (impact) car was not attentive? Our field of vision looking forward is "V" shape, and because the blue car was wayyyyy on the left, the woman probably wasn't in his initial "arc of fire" and could have literally appeared in an instant to him (i.e. come into his vision) because she was running some more. How to react?
