I had intentionally bowed out of this "debate" because of some of the brick wall attitudes and so lost interest, but I can't help myself.......
To suggest that this law is a stepping stone to banning bikes is ludicrous, and nothing but desperate straw clutching. Do the freedom fighters turned fear mongers really think that if eg Obama one day said "ok guys, enough motorcycle deaths...lets ban motorcycles" that it would only apply to the states that DO currently have mandatory helmet use? I think not, so how then did the helmet laws become a stepping stone to the banning of bikes? Given the numbers of motorcyclists in each state, do you think a governor candidate (called premiers here) would risk the political backlash and loss of votes (or protest votes) that would come with the decision to ban bikes? I think not. They have successfully introduced mandatory helmet use in most countries and US states, because right minded people see it as a sensible and inevitable move, regardless of their personal opinion. Some laws are actually good for us.....believe it or not.
I haven't seen one of the anti law protaganists give any reason why they think the laws were introduced in the first place (I'd be interested to know what they think)....it's all about me me me, my rights, my decisions, my.....Perhaps more thought should be given about the costs and impact on society in general - the society in which you live and pay taxes in and, oh hang on, obey laws in - not just their own little precious worlds. The laws were introduced for a reason, not just because some politician thought it up one day to just piss off some bikers.
In this country, and all over the world, seat belt wearing in cars is mandatory - does anybody think the introduction of that law (back in the early 70s here) was a stepping stone to banning cars? I think not. It was introduced to help prevent death and serious debilatating injury - it also reduces serious brain injury resulting in once happy and fulfilled people spending the rest of their lives being spoon fed by their children. It has worked. Yes of course, there are still rehab centres full of brain injured drivers, but one can't imagine where'd we be if people were allowed to choose whether or not they wear their belts. There just wouldn't be enough beds.
The same principle applies to helmets - it would be a hard stat to derive, but the fact that wearing a helmet decreases the risk of brain injury is irrefutable. I, and many others, would not be here today if we didn't wear a helmet. If people are given the choice of not wearing one, the clowns of the world will then ride on public roads with no helmet because they can - they are then increasing their risk of acquiring a serious brain injury - that also can't be refuted. This is why governments introduced mandatory helmet laws - to help reduce that risk and save the lives of people who should (or don't) know better, and thus help keep a few empty beds in our rehab centres. The cost of brain injury to society is huge - not just in ongoing health care and the cost of support workers needed to feed, wipe bums, wash and dress these poor unfortunates, but in what it does to families and loved ones. If you had respect for these people you'd understand why some people need to be TOLD to wear a helmet. We can't have laws for some and not others, so we all need to live by this law, we are not all reduced to the lowest common denominator as has been suggested - the naysayers are actually elevated to a safer way of living.
For the record, I am a motorcycle instructor and part of what I do is preach the wearing of helmets and protective gear to learner riders, and praise the fact that we have laws to enforce helmet use. None of them, in my experience, have ever argued with that.
