Another reason is that being really respectful around cyclists is an important part of driving lessons in The Netherlands. And I think you can fail your driving test if you pass a bike too close, open your door without looking if a cyclists is coming from behind, or passing over a bike lane at an intersection without looking. I am from The Netherlands and I only realized since moving to Canada that my home country is…
>I find it interesting that no one in The Netherlands wears a helmet when cycling and yet serious cycling injuries don’t seem to be a common thing Neurosurgeons in the Netherlands disagree with this, and are begging locals to wear helmets. https://www.dutchnews.nl/news/2021/10/neurologists-launch-ca... I don't know how rates of injuries compare between countries, but that is irrelevant.
Here are some important conclusions:
1) Cycling as a commuter is quite safe, with or without a helmet.
2) Cycling is safer with a helmet.
3) If you found yourself in some binary where your only options were "cycle without a helmet" or "don't cycle at all", the health benefits of "cycle without a helmet" likely outweigh the risk of serious injury due to not wearing a helmet.
4) Because of #3 and other factors, helmet laws for adults aren't generally a net positive.
5) BUT - it's a good idea to wear a helmet whenver you can, and even the Dutch (fore example) would be better off if they kept their usage of cycling high, but culturally embraced wearing helmets as well.
6) Things are very different in higher-risk forms of cycling like BMX, road racing and MTB, where crashes are much more frequent and higher impact, and you'd be an idiot to not wear a helmet.
