A concise explanation from Urban Country on why bike helmets really aren’t warranted. First, cycling just isn’t that dangerous, and we do most safe things without a helmet. Second, strongly promoting or legally requiring them discourages cycling in general, and fewer bikes on the road is less safe for cyclists, less healthy for society, more expensive in terms of infrastructure, pollution, etc. Third, bike helmets aren’t really designed to deal with serious accidents — the ones that kill or maim you. And fourth, focusing the blame for what danger does exist for cyclists on the cyclists themselves, distracts from the real bicycle safety issue, which is cars.
