When I was in primary school and maybe high school I remember not wanting to wear a helmet because it looked silly. As a adult I think it would be a lot more silly to loose my life, health, ability to focus or to walk just because I didn't want to look silly. I'm not saying you are wrong, but that all people you know are. Besides the helmets these days really do look better, the producers have moved on from a purely utilitarian focus to actually having someone think about the visual aspect as well.
Yes, I have and it's great. Similar to Denmark where I live, but it's even safer if you wear a helmet. There is a clear benefit to wearing one and not much of cost so it's an easy choice IMO.
I haven't been to Denmark (yet, will be in CPH in Nov!) but I understand ytour cycle infrastructure is comparable to that of the Netherlands. Do you find more people wear helmets there than in NL?
