I hate seeing people riding without helmets in the US, kids or adults, path or road. And I absolutely always wear one here -- would feel naked without one. But interestingly, in Belize, where literally NO ONE wore a helmet, it didn't bother me because it was just the cultural norm. I admit that I also did not wear a helmet there. There are few vehicles (mostly other bikes and golf carts), and because of bad roads, speeds are slow. Riding a beach cruiser on the sandy beach path and even on the bumpy road, I never worried about not wearing a helmet and never had a problem. I did fall a couple of times in the sand (slow speed spin out type falls), but never hit my head. I know many of you here would not have even taken that much of a chance, but culturally, being from the US, we were already "different" enough, that I just didn't care to stand out even further from the local crowd. When in Rome, I guess...
