One thing I've never understood from a physics perspective:  Why not have padding on the outside of helmets?

The padding on the inside helps when recieving hits, but having, say, 1/2" of dense foam around the helmet could increase time of impact (reducing impulse) and spread out the area of impact (reducing pressure) for both recieving and delivering hits.

I'm sure this wouldn't solve the problem, but it seems like an easy step in the right direction.
