For most bikers, this advice is anathema. The importance of
wearing a helmet has been drilled into everyone since childhood.
And, it’s true that, as study after study has shown, you’re better
off with a helmet if you’re in an accident.
But in the world’s most popular biking cities, particularly in
Europe, very few bikers wear helmets. And there are good reasons
for that: biking, it turns out, isn’t an especially dangerous form
of transportation in terms of head trauma. And the benefits of
helmets may be overstated. While they do protect your head during
accidents, there’s some evidence that helmets make it more likely
you’ll get in an accident in the first place.
