Was this on the article that was about the complicated nature of do helmets make people safe? For hints to people searching I remember it was something about drivers acting differently around people with helmets and non-helmeted cyclists (I don't think the article made hard assertions of what was safer, but boy did the comments. It definitely suggested you should wear one). What I do remember is that the comment section was a complete and utter shit show with people saying cyclists deserve to get hit by cars (but isn't that always true for comment sections including cyclists?)
