First off: I always wear a bike helmet on the pushy - partly because if I ride, I try to keep my speed up. I also did this in the UK years ago, where helmets are optional.
But I actually don't think what I am doing makes sense and here's why: unlike say seatbelts or airbags in cars and motorbike helmets, bike helmets are not statistically proven to work, to the best of my knowledge (
Example). I'd be happy if you could point me at research that proves that they are beneficial.
So we are in the realms of opinion with regard to their efficacy. At least one neurosurgeon thinks they are too flimsy to have a material benefit. (
This guy here.). And in
Canada there is no evidence compulsory helmets had a material effect on head injuries.
However there is research that shows:
1) The more cyclists are on the road, the safer all cyclists become through habituation (an argument that we sometimes employ as motorcyclists). (

2) There are health benefits in cycling as a cardiovascular exercise and it also helps with weight control. These reduce a multitude of other risk factors and dissuading people from cycling reduces those benefits. (
Example)
3) People are
dissuaded from cycling by mandatory helmets, which does not help either point 1 or 2.
4) Motorists tend to pass cyclists wearing helmets
more closely than those not wearing them (perceived risk is lower, perhaps), thus increasing the risk of impact by a passing vehicle.
Getting hit from behind is not a good scenario for broken bones and organ damage which of course can be severe. Neither is it good for the head, injuries to which may be even more devastating. But if helmets are actually too flimsy to help, why make them compulsory? You could really put people off cycling by making motorbike helmets the requirement. At least there is statistical evidence that they help. Multiple compound fractures, blood loss and organ damage may well kill me instead.
My personal experience cycling in Auckland is that in the end the Russian Roulette aspect got me off the treadly. I started out believing that it was unlikely that I'd get hit and ended up believing it was only a matter of time, due to the frequency with which I found myself a gnat's whisker from being hit from behind. I was also once cycling uphill when I was punched in the kidneys by a passing hoon, I also had beer bottles thrown at me on many occasions and was "shaved" with the horn blaring "for a laugh" very frequently. I hasten to add that I was always in "good" suburbs, cycling alone and keeping left (not being a bloody-minded obstacle). It wasn't helmet law that put me off, it was the mindless aggression.
I also rather believe that the more friends and family we have who we know ride bikes, the less aggressive we will be towards strangers on bikes. That's just an opinion, but to me it seems logical.
So I'd like the helmet law repealed and to see more people on bikes. I think that would be a good thing, for the reasons stated above.
