I didn't watch the vid. But I can easily visualize.
Stuff like that never fails to baffle me.

A couple years ago in Central CM (Loi Kroh Road. Intersection (there is a police box there), just past the canal bridge.
Walking. I approached the corner sidewalk area at the intersection. No traffic, yet I pause anyway (I suppose habit). I sensed something.
Then I hear a motorbike whizzing along travelling toward the intersection. Something seemed odd. It was the sound, it wasn't slowing down. I waited with one foot on the roadway, the other on the curb, still in pause mode.
A small car comes from the cross direction, enters the intersection. The motorbike impacts the side of the car. The bike shatters into dozens of pieces. The bike driver flies over the car, bounces off the pavement and lands about a yard from my foot in the roadway.
The bike driver was screaming and writhing in agony.
I thought to myself. "Well, at least he is screaming. He will probably make it."
