His skull is bigger with more fluid and more ligaments, which act as an inbuilt safety mechanism to support the brain when a collision occurs.
The skull is almost helmet like. It absorbs a lot of force on impact by fracturing, which stops the force from carry through to the brain.
When a pedestrian is hit by a car when stepping out from a curb, the immediate problem is that the knee will always break first because it is only built to bend in one direction. But in fact, from what the force of impact can tell, the tendons can also pull, twist and hyperextend well beyond their intended radius.
This is especially important for motorcyclists and cyclists, who have only little protection between themselves and the road.
