Here are some statistics for the few here that like to claim they are on there side. Statistics are only as good as those who take them, but it looks like this site did a little research.

Here's a couple I thought were interesting.
7. The failure of motorists to detect and recognize motorcycles in traffic is the predominating cause of motorcycle accidents. The driver of the other vehicle involved in collision with the motorcycle did not see the motorcycle before the collision, or did not see the motorcycle until too late to avoid the collision.
15. The median pre-crash speed was 29.8 mph, and the median crash speed was 21.5 mph, and the one-in-a-thousand crash speed is approximately 86 mph.
19. Motorcycle riders between the ages of 16 and 24 are significantly over-represented in accidents; motorcycle riders between the ages of 30 and 50 are significantly under represented. Although the majority of the accident-involved motorcycle riders are male (96%), the female motorcycle riders are significantly over represented in the accident data.
23. More than half of the accident-involved motorcycle riders had less than 5 months experience on the accident motorcycle, although the total street riding experience was almost 3 years. Motorcycle riders with dirt bike experience are significantly under represented in the accident data.
30. The large displacement motorcycles are under represented in accidents but they are associated with higher injury severity when involved in accidents.
