Carwyn Hooper – a medical ethicist – in the Guardian’s bike-blog on helmets:

… the most ferocious debate about the effectiveness of helmets – and the legitimacy of forcing competent adults to wear them – centres on cycling. It is not entirely clear why, but it may have something to do with the growing popularity of cycling as a sport combined with the visibility and ubiquity of “commuter cyclists” in our everyday lives. Whatever the reason, the debate about the relative effectiveness of cycle helmets is fierce and the debate about their mandatory use is even more so.
