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.
