No doubt about that, Jerry. I think the government does have a role to play in the safety of it's citizens...granted, it's a fine line to walk, and constantly being redrawn, but I didn't want to wear a seatbelt either...now I unconsiously buckle up. It's not about freedom to choose...I may be playing Russian Roulette every time I get on a bike, but my gun just has one bullet instead of two...
This is where the numbers come in to play again though. Large numbers of people in cars. Large numbers of real and potential liabilities for not employing contemporarily standard and accepted safety measures. So lobbying efforts diminish that worked against regulators mandating belts, air bags, etc etc etc. What regulators wished, but could have only gotten done more slowly, they were allowed to do because the numbers/costs involved now suggested that going along was the better option.
With helmet laws it is, or it can be, a different numbers game though. The road, writ large, isn't built for the motorcycling public as its first consideration. That's a given and without dispute. Yet we get to use the road system for no greater cost than our cage riding compatriots. For that privilige we thank the road builders (government) and try to stay out of their way in the hope that they'll stay out of ours and give us as little attention as possible.
It can't be argued, however, that we (bike riders) don't have a disproportionately greater number of injury accidents per miles driven than cage drivers. It's just a matter of fact. Nothing new there so nothing to argue about. What that translates to, however, is that we "cost more" per miles driven than the cage driver. Our overall social cost is greater because our injuries and their concomitant cost on society are more common and greater.
That being so governments have a real right to regulate us. Some would even say they have a responsibility to do so. We cost others so we should be made to be as safe as possible. That being so it begs the question why don't all jurisdictions require helmets? It's again because of numbers. Relatively speaking there are few enough of us that the extra costs we incur are borne without hardship or harm to the local and larger communities. But know for a fact that if we got too loud and obnoxious, or too expensive, all that would change in a heartbeat. There's just not enough of us to turn the tide otherwise.
We are not who the road builders build for (nor, given our numbers, should we be). We are not society's primary responsibility on the open road. Those responsibilities are the national economy/commerce those roads facilitate and the machines that make those go and the families of four that make up the large majority of the rest of the motoring miles covered. We do ourselves the best service when we recognize our potential relative costs versus the gains we enjoy by having that great road system open to us. Then we best ought just keep our mouths shut, enjoy the sunset on the horizon in front of us, lean back, put our feet on the pegs and enjoy the ride; even if we have to wear a helmet to do so.
