TO Chris Roughneen
If you go back to my original post you will see that somebody was bound to say it was the car drivers who caused most of the accidents and that if the overriding aim was to cut the fatality rate then banning motorcycles from public roads was the one things guaranteed to work. Didn't mean that I was really saying that they should really do it - just recognise the effect. Even if the statistic of just over two-thirds of accidents being due to motorists is true (and I'd want to see exactly what they are measuring here and how - self-interested motorcycle insurance specialists aren't a naturally unbiased source) and you adjusted out the effect of the extra accidents caused by motorists (so it was 50:50) would would still get a vast over-representation.
In fact this guy here states (from a US study) that 41% of motorcycling fatalities do not involve another vehicle. Apparently more than twice the number than any other cause. Well maybe these 41% don't make an insurance claim which, if true, immediately makes a "nonsense of the 70% are caused by motorists argument".

OK - it's an old report (1994), but given that fatality rate among motorcyclists has fallen far slower than for road deaths as a whole, then is it really the case that there has been such a turnaround? Here are a few sentences from the report:-
"MOTORCYCLES The 2,304 motorcyclist fatalities accounted for 6 percent of total fatalities in 1994. The motorcycle fatality rate per 100 million vehicle miles traveled is about 20 times that of passenger cars. Motorcycle operator error was identified as a contributing factor in 76 percent of fatal crashes involving motorcycles in 1994. Excessive speed was the contributing factor most often noted. "
Here's another more recent one from 2005 (again American). 44% of motorcycle fatalities did not involve another vehicle

So even if you eliminated all the motorcycle/vehicle accidents which were caused by the other vehicle driver (not all of which are cars) then 63% of all these motorcycle deaths are still attributable to the motorcyclist.
Then there is this one :-

"Motorcycles are also more likely to be involved in an injury collision with a fixed object than are other vehicles. In 1996, 15 percent of the reported injury crashes involving motorcycles were fixed object crashes, compared to 8 percent for passenger cars, 8 percent for light trucks, and 5 percent for large trucks."
"In 1996, 42 percent of all motorcyclists involved in fatal crashes were speeding, nearly twice the rate for drivers of passenger cars or light trucks. The percentage of alcohol involvement was 50 percent higher for motorcyclists than for drivers of passenger vehicles."
Even if motorists did cause most accidents involving motorcycles, then you also ought to ask why this happens. Motorcycles are, of course, simply more difficult to see than cars or lorries. That's just a fact and no amount of "education" changes that. Maybe you can train everybody to be more cautious, but the disproportion will still arise. The "simply didn't see" syndrome is always going to happen - human beings are fallible. You can make it less likely to happen, but you can't eliminate it.
As for the fuel-efficiency of motorcycles, then there are plenty of people I know who get around 40-45mpg out of sports bikes (sometimes less). My rather old diesel car (which is far from an economy model) average 45mpg. Yes, you can get more economical motorcycles but the guys I see every day on the motorway weaving their way in and out of traffic, down white lines, across hatchings are not, in general, riding those type of bikes. So if you want to make a green case, ride one of those 100mpg bikes, but if you have a Hond Fireblade you are on weak ground (and that's even before you taking into account the difference in load and passenger carrying capabilities).
No, almost by their very nature, riders of high-powered motorcycles are less likely to be risk averse than road users as a whole. If safety was their prime concern then they simply wouldn't be exposing themselves to the extra dangers. My day-to-day experience is that this is the case. It was also my experience as a young motorcyclist (and we all know we are immortal at that age).
