There has been a long debate about the accident stats of LD Riders. The picture is not clear, and the pool of stats is relatively small so it's hard to determine if there is much significance.
In our favor is that as a group we are older than average, better prepared, more experienced, better protected and ride quality machines. Much of the mileage is on limited access highways, which are the safest roads. All of that should put us in the lower risk group, which it probably does, but then we go out and take more risks.
We ride further, for longer and in conditions that most riders would not be on a motorcycle. And yes, we ride when tired, let's not deny it even if we still seek to mitigate the effects of that.
Even a cursory look at the incidents during rallies suggests that "get-offs" are not infrequent. Probable that injuries are minimized due to good gear and decent skills, but still they happen. What is more, far too many of those incidents are "single-vehicle" events suggesting that the rider bears at least some of the responsibility.
During the last Iron Butt Rally there were a number of accidents ranging from a deer strike to a 30 mph low-side in traffic (no explanation of how that happened to one of the most experienced riders on a well-sorted Gold Wing). Yet another rider hydro-planed his nice BMW out of the rally on Interstate 95, at normal speeds. .... Still, add them up and the rate per 100 000 miles is not dissimilar to the population as a whole. While that is just one rally, and on its own proves nothing, the pattern is repeated across the sport.
It may be that attempts to compare stats is a pretty useless exercise, because what we really need to do is minimize our own risk, on our next ride. However skillful, well protected and well prepared we might be, accidents still happen and like as not they always will.
Grim as these discussions are, if they raise awareness they help. Tony is right, there may be an element of "whistling past the graveyard". But if we are going to do that, at least let us keep our eyes open.
