I live in Indonesia. We have the highest per-capita rate of bike ownership in the world.
I have seen what happens to motorcycle riders when there are accidents and I have seen what happens to car drivers when there are accidents. I won't get into the gory details but I avoid using bikes as much as possible.
And I've seen what happens when pedestrians get hit by a car going way too fast, it sucks, and is horrible, but also besides the point. Not to say one has worse/better accidents, motorcycles accidents obviously has a much higher fatality and serious injuries risk, hard to deny.
