If you do deeper research you'll find that many motorcycle crashes are alchohol related, and many crashers have no licenses.
It amazes me though that the report says nothing about road user education. This have been proved time and time again to reduce crashes and deaths, yet all they talk about it more safety crap in cars and better road engineering. What about distractions, impatience, and ignorance? These obviously cause an enormous amount of problems, but we'll just not worry about that right now as the problem gets worse and worse...
