I've pointed out before that I'm a skeptic about the potential for bike share schemes because the numbers just don't add up to a significant culture of cycling.
I also rarely post about helmets, as I see them more as a symptom of a problem, primarily that there is inadequate subjective safety which causes people to see a need for safety equipment.
However, Mike Rubbo's latest blog post and film, makes an excellent point that compulsory helmets and bike share are fundamentally incompatible. Neither can exist with the other.
Incidentally, we had a film crew here in Assen yesterday who only after the shoot realised that they'd not worn a helmet as they would have in the UK. It just doesn't feel necessary to wear one in somewhere like Assen.
