As a motorcycle rider (every day commuter) I often think that if motorcycles didn't already exist, they wouldn't be allowed to.

As per sibling comment, maybe the only reason they are tolerated is that the risk is statistically largely to the rider themselves.

IE the person taking the risk is largely the target of the consequences.

If motorcycles somehow magically penetrated into peoples cars in a crash I think people would rule them out pretty quick.
