Own worst enemies?
I've only ridden over the woundrous Cat and Fiddle about half a dozen times, once during a BikeSafe course. Each time it's been a bit cold, gloomy and damp in places, so there were't all that many other bikers out there, but I've already come across a self inflicted casualty: one misjudgement, a damaged wrist and a damaged 600 sportsbike - an own fault single vehicle collision - fortunately the outcome wasn't very serious, but statistically it won't be recorded. But it's a symptom, and I dread to think how this extrapolates to the height of Summer. I'm not sure I want to witness the carnage.
What of all the floral tributes I ride pass at the sides of the road on the Snake Pass and Woodhead, always near tempting bends, how many of these are testimony to the misjudgement of a victim who is also the only villain?
Nedd, I'd love to see some real statistics, properly interpreted, but I don't think it would help your argument.
As for the science of our destructive power, a two up (350kg) Hayabusa at 122 mph (taken as a random example for illustration...) has a kinetic energy of roughly 520 MegaJoules - enough energy to make quite a mess. A two up family hatch (1600kg) at 60 mph has kinetic energy of around 575 MJ, not so different... Remember, travelling 41% faster doubles your capacity for destruction, travelling twice as fast quadruples it. Travelling faster also reduces your chances of being seen in time, and limits your opportunities for avoiding the unforeseen, so the chances of all that kinetic energy being dissipated in a really bad way, rise too. From my experience a big chunk of the biking polpulation like to travel faster, much faster, and being much freer to overtake, often do so.
As a population I am absolutely certain that we motorcyclists include own worst enemies. We are collectively much better at accidentally harming or killing ourselves than any other group of vehicle users. I'm equally certain that speed restrictions and enforcement won't help, but I don't think we can expect any stats to show us in a glowing light.
Perhaps we do need preaching to?
