Cycling in Waterloo Region

No, it certainly isn't "always" good advice (in the Netherlands, its statistically bad advice, but really, it's wasteful advice).

You are assuming a causal relationship where one doesn't exist.  Correlation does not automatically imply causality.

No, of course correlation does not imply causation, and you are right, I was referring to the fact that wearing a helmet is correlated with being injured in a cycling accident in the Netherlands.  That doesn't mean wearing a helmet causes injuries, but in fact means that only people who are sport biking wear helmets, and they are more likely to be injured.

But I still don't know that wearing a helmet in the Netherlands is a good idea.  At the very least, people will look funny at you, and you'll muss up your hair, and maybe you'll be less likely to bike.  Certainly it is not "good" advice, as I said, it's at best, wasteful advice.
