Are YOU satisfied with any statistical study that ever recorded, measured or provides a clue on the type of equipment worn/not worn when cyclists were NOT injured "seriously" enough in bicycle accidents/falls/crashes to require a hospital visit? If so, which study or survey was that? Or are you like one of those old wise men who doesn't need no stinkin' facts to be thoroughly satisfied that his biased opinion is all the stinkin' facts anybody needs to know.
