This article by fellow-MAMIL Michael O’Reilly makes an argument I’d been meaning to post. Whatever the merits of bike helmet laws in general, the costs clearly outweigh them in relation to bike-share schemes like CityCycle in Brisbane.
We clearly need a category of exemptions that lets people hire a slow bike for touring around our cities. Having done that, I’d extend it to anyone willing to take the trouble to apply for exemption, while maintaining the helmet rule as the default. I certainly wouldn’t seek an exemption – I like my head the way it is – but I can imagine there are people who would make the choice, and it’s not so obvious that their judgement should be over-ridden.
