I understand where Grant is coming from regarding helmets, but he's confusing several different hypotheses about helmets into one confused hypothesis if one is contemplating whether to wear a helmet or not: 1) Does wearing a bike helmet reduce or increase incidence of serious injuries, and which kinds of injuries? 2) Does wearing a bike helmet cause or prevent serious injuries, and which kinds of injuries? 3) Which types/models of bike helmets are better or worse at causing or preventing serious injuries? 4) Which models of helmets are more durable? 4) Does wearing a bike helmet result in a reduction or increase in reckless cyclist behavior? 5) Etc, One can always avoid becoming a reckless cyclist oneself once you place a helmet on your head.
