Yeah but the glass breaks really easily so it should help disperse the impact.

The overall height, especially of the hood is also really important for the pedestrian's chances. if a sedan hits you, ideally you can roll over the top. if a truck or suv with enough size hits you, you go under it.

Somehow I think the mass and speed is far more significant than a pointy bumper.

Mass probably is only significant because it makes the stopping distance longer.

Mass also adds to the force of the impact
