If I had an experience of being seriously injured on one of the few times that I wore a certain piece of clothing, I think I might realise that that clothing might not be as great as it's claimed to be and investigate the evidence and statistics.Last year I was on the way out and remembered it for the firt time in weeks. On the way home I had a big off and realised the big deep scrapes and broken peak on my helmet would have been my head and face. As it was, I ended up having an operation on my hand and staying in hospital for 4 days.
I never leave home without a helmet now and I wonder how many riders have got to have an experience like mine before they realise that riding with a helmet is not a bad idea after all.
As it was, it took much longer to connect a neck injury with helmet use, then look at the evidence and stop using.
