To all the armchair experts: try recreating this accident scene in the real world.

Sodium Vapour (monochromatic) lamps, then a large darker area with a pedestrian in dark clothing with car’s headlights dipped.

You will be alarmed at how much stuff you can put on the road and not see it because the road has a lighting pattern that makes it less safe than no lights at all.

With no lights at all, and a hedge between carriageways, the car would have had high beams on and the driver may have seen the pedestrian with plenty of time to brake and either avoid collision altogether or reduce the impact to non-fatal energy.

Now go recreate the scene for yourself and see how it works for you.
