I read several articles surrounding Australia's situation yesterday to educate myself but still find the whole thing curious. As a cyclist I've never taken on more risk or rode someplace I otherwise wouldn't just because I'm wearing a helmet, and as a car driver I've never thought to myself "Hmm, that cyclist is wearing a helmet, guess I'll clip that mothersmurfer a little closer." If the researchers are to be believed however that makes me an anomaly. All I know is that after a car driver turned right just after passing me in 1991 and I somersaulted over the hood of their car at 45 km/h, I have worn a helmet, and I will never feel safer not wearing it.
