I'd like to see where those stats came from... It's not that I don't believe you, but you know what they say about statistics. I mean there are probably people who wreck on some back road, their head (with helmet) hits the pavement and they get up and ride away. It never gets reported or added to some tally somewhere, and nobody is the wiser. Whereas if they didn't have a lid, they'd be in an ambulance getting added to the other tally.
