The vast majority of Dutch people cycle, but almost none of them wear bike helmets. This surprises Germans and Americans, for example, because bike helmets are mandatory in those countries. But the Dutch say helmets are unnecessary given the abundance of safe bike paths.
Additionally, helmets are not considered cool and they are bad for hairdos. Nevertheless, some are calling for helmets to be made mandatory in the Netherlands. This could potentially benefit the hundreds of young children who land in hospital each year suffering from head injures from bike accidents.
