That's called confirmation bias and is a horrible way to build policy. I would, however, fully support regulations that required more education and smaller bikes for new riders. Even solo-riding age limits (can't ride alone until you have son much experience and age) could be useful. Squidly behavior (stunting and the like) should not be tolerated (more closed circuit roads would help, as it did with drag racing).

However, regardless of how bad somebody is riding, when something goes wrong, the rider always loses. Also, something that may seem "dangerous and aggressive" to you may be the best way for a rider to get out of a dangerous situation. I use the acceleration and maneuverability of my bike to escape e.g. being boxed in by large trucks on the freeway. I'm just taking advantage of the escape hatch before something goes catastrophically wrong.

I have seen a few crashes involving motorcycles not paying attention or taking unreasonable risks. Overtaking on blind bends etc. I haven't seen anywhere near the same number of crashes involving cars.

Is that confirmation bias as well?
