Alright, so addressing the original question.
@Mtns2Skies there are absolutely a number of motorcyclists who are not very good, inconsiderate, and don't seem to have any clue of what they should be doing to keep themselves alive. It almost seems like motorcyclists are made up from a similar pool as the rest of the world's population.
Because there are fewer motorcyclists, the idiots are more pronounced than for cagers, where we come across them all the time but don't think much of it because they're so common.
The one thing I'll respond to specifically is on speed. When I'm on a motorcycle I'll typically just go the speed limit these days. Reason? I'm just enjoying the ride and I'm not trying to get where I'm going in any kind of a hurry. Now I don't get annoyed if anyone passes me (so long as they do it legally and don't try to get close to me) but it's not that we can't go faster, it's that we don't necessarily want to. I'll even go the speed limit when driving my cars most of the time, too. When I was your age I didn't understand that so much, but it is possible to enjoy the ride/drive without going fast. I also drove a lot more back then. These days, I drive a lot less than I would like to, and I ride even less.
