Wearing a helmet can be demonstrated to be more effective in terms of number of lives saved by being worn by pedestrians and motorists, rather than cyclists. Are you saying that we should all wear helmets when out in public?
I am saying only what I said, if you doubt you can read it again above.
The numbers you are referring to[1] do not mention lives saved but rather head injuries by transportation modes. They say nothing about seriousness of the injury. And I am pretty sure that when biking downhill at 70km/h chances are that a head injury will be more serious than the one i'd get by falling on the sidewalk while walking. I actually hate using a helmet while biking, and often go out without one when I am biking at a leisurely pace. But when I go out to train or to get to places fast, I prefer wearing the helmet.
