Sometimes. And sometimes the problem is a loose nut holding on to the
handlebars. We've all seen the idiots riding the wrong way against
traffic, the wrong way down one way streets, blowing through red lights
and stop signs, riding in dark clothing without lights or reflectors at
night, riding with no brakes, etc. The term "contributory negligence"
applies.
