Could not agree more. After Holland, which does quite well without the helmet nonsense, I haven't been on a bike at all. I will not wear one of those things just to tool around our quiet country roads. There are so many things that can kill you. I don't want a nanny state managing my risk assessment for me. Children are another matter, but adults should be treated as such and allowed to make their own choices.
They also make any citibike type short term rental scheme pretty useless since people dont tend to carry helmets just incase they want to rent a bike to get across town.
