Taking a look at that report, it seems to be missing an important statistic when it comes to motorcycle crashes.

What is the fatality and serious injury rate when comparing when the motorcyclist is at fault vs when the other vehicle is at fault.

An accident involving just a motorcycle, intuitively, seems a lot less likely to be fatal to a properly geared person. Often times such an accident will be because of operator error and result in a low-side crash. Crashing into something on the road could result in serious damage, but that's a lot less likely than losing traction and falling off. If I recall correctly, the Hurt report supports this.

Similarly, in a two-vehicle accident where the motorcyclist is at fault, the motorcyclist is likely to see it coming and attempt to prevent it in some way. Additionally such a statistic will also include motorcyclists low-siding and then their motorcycle (or them) sliding into a vehicle.

Overall, it seems believable to me that while a in majority (56% isn't even that much more) of motorcycle crashes the rider is at fault, if we take a look at only fatal crashes and crashes resulting in serious injury, cars will bear the majority of the responsibility.

All that said, I also find that report to be a bit alarmist and disingenuous with statistics, particularly when compared to the Hurt and the MAIDS reports. I would assume this was done in the interest of "scaring" riders into safer behaviors and not with any malicious intent.
