I think the fact that we made it so far without such protection from the minor injuries that can result from simple falls speaks for itself.
A quite valid point, I believe. In another thread in A&S we discussed the relation of speed to the severity of crashes between cars and bikes, à propos links to "twenty is plenty" campaigns. It seems that we're "build" to generally withstand falling/hitting our heads at up 'till 20 mph, which is just about the maximum speed a fit young man can run. Above that speed, injury rates and fatality increases exponentially.
