IMO the most important aspect of this whole debate is money. Lots of money is made from manufacturing and selling bicycle helmets. That's why the bicycle-naive general population only knows about helmets when asked about bicycle safety.
Given that skills training, traffic engineering and other key components of real (i.e., statistically defensible) bicycle safety are not profitable how would you go about fixing this dysfunctional aspect of our automobile-centric cultures?
