I don't necessarily agree with op, but you rarely see cyclists with helmets in amsterdam and other dutch cities where a lot of people use cycling as their default transportation method, and where as a cyclist you have a priority over car drivers, whereas in places like berlin you have much more cyclists wearing helmets, and rightly so. Though I have to say that I myself only wore the helmet while working as a bike messenger, and rarely while not. So obviously on a day where I'll be biking for 6-8 hours I'm more likely to get into an accident, helmet or not.

Ah, ok, I'm starting to see a different perspective on helmet use: comparing cities rather than individuals in a city.

Perhaps the studies should differentiate these: i.e. comparing accident rates of helmets against non-helmets within each city individually, vs comparing e.g. non-helmet-users in Amsterdam against helmet-users in Berlin.

I live in Dublin which, as mentioned in the article, has recently seen marked improvements in cycle safety. Helmet usage here is high but under 50% and seems evenly distributed. I'd be curious to see the stats on what the means for accident rates local to here.
