Bicycle Dutch has a selection of news:
Velo-City is a conference on June, 13 in Nijmegen, NL. Because he’s not flying for KLM on that day, Willem-Alexander will open the conference.
Also, the Dutch View on cycling helmets:
Take the bicycle helmet. If you make it mandatory, you strengthen the idea that the bike is a dangerous means of transport. That leads to a decrease in the number of cyclists. That again decreases the safety, because the more cyclists there are, the more other road users will consider them. In short: the bicycle helmet increases the individual safety, but decreases the safety in general.
I have yet to see Dutch people riding their bikes with helmets on.
