I never liked helmets and refused to wear them even as a young adult, but now that I have a small child I got myself the dorkiest, safest high-vis bike helmet I could find.
The stories I hear how helmets save lives typically don't involve other vehicles - my personal is actually from skiing, as I borrowed a helmet from a friend who had to end his vacation early and I think that saved me from a severe concussion, because a few hours later I fell face-first on compacted snow and couldn't get myself together for a few minutes afterwards.
> that makes using OV-fiets, etc. more of a hassle.
Perhaps, but are we about road safety or are we about popularizing cycling, traffic deaths be damned?
My manager uses a rental bike to commute and he always has his helmet on when phoning in during a break in his commute because he has three kids and no intention of orphaning them.
I see it as a question of priorities. I'm against car-oriented infrastructure because I believe some people(20% at least) really shouldn't drive and I care about safety. Bicycles don't seem to deliver on that front either - at least until we figure out what's causing this increase and why the heck aren't all these seniors using public transport?
