The most thoroughly investigated PTW mishaps in the US are those that involve fatalities.
This study from Washington State is consistent with other studies of the subject in the US. In so far as fatal PTW mishaps, the rider is the most common cause of the mishap, not another driver.
The brief summary (emphasis added):
Quote:
Data reviewed by the Task Force indicated that:
The vast majority of fatalities occur during daylight hours, in dry weather.
More than 80% of fatalities occur between April and September, prime months for motorcycling.
Half of fatal crashes were single vehicle occurrences; no other vehicle was involved other than the motorcycles. When alcohol is involved, two-thirds of fatal crashes are single vehicle occurrences.
The most common contributing factors to motorcycle fatalities, based on law enforcement scene reports, are lane error, speeding, alcohol and inattention.
A third of fatalities were motorcyclists who did not have a valid motorcycle endorsement.
Conclusion
The Task Force concluded that, while there are multiple contributions to motorcycle crashes that result in fatalities or serious injuries, it appears that the most important factors are within the control of the rider. Efforts to reduce fatalities and serious injuries should focus on rider skill and behavior.
In short, the rider and his/her attitude, skill and judgment are the significant determinants of the risk level experienced in PTW riding.
Mishaps are CAUSED. Eliminate the CAUSES and there will be fewer mishaps. The serious research consistently identifies the rider as the CAUSE in fatal PTW mishaps.

P.S. I would also add that there is a
significant difference between SAFETY (mishap prevention) and survivability equipment. Helmets and gear do not make you safe, but they might, within their design limits, mitigate the injuries an unsafe action can cause.
