You have stats to back that up? Because the stats say that the use of bicycles has declined steadily since 1994. And consequently there has been a reduction in cyclist injuries. Which the helmet-wanters have misinterpreted as justifying helmets.
Yes. The bike shed was just as full as it ever was. Maybe people weren’t as vain back then for it to even be an issue? In fact at that time a whole new range of lightweight helmets had come out and they were seen as ‘cool’ to wear, especially compared to the old stack hats and pro elite helmets.
