Man. This is just weird. Once again, where do you get this idea that you are the more important one in this situation and deserving of respect, yet you can just call other people a "nuisance"? The situation you describe is so obviously an issue of infrastructure — bicycles have always been street legal on roads such as the one you describe, yet the road was planned out under the assumption that no one would ever try to ride a bike there. That sure as hell isn't the bicyclist's fault, regardless of how inconvenient it is for you and other drivers!
Or to put it another way, that wouldn't ever be a problem in, say, the Netherlands, where even country roads have parallel bike paths that ensure both their safety and the free flow of car traffic. Blame short-sighted planning where you are — if you're in the US as I am, you should be well aware that's the American way, especially when it comes to infrastructure. I'd go so far as to call it a national embarrassment, the amount of time and money we've put into systems that weren't built to scale.
Another thing: Because I'm used to bike commuting and the half-decent cycle infrastructure in the city I live in, when I drive I don't take getting stuck in traffic as a normal part of life. I once lived in LA, drove every day, took it as a given, but I can tell you if that's not the case, boy does it suck. Way more than the occasional slowdown due to a cyclist on a shared street, or the occasional cyclist pulling stupid shit at an intersection. That affects you for a short while and then it's gone. Traffic slows you down for a good chunk of your trip on a daily basis and is a proven stressor, so much so that many drivers become numb to it just in order to deal with their lives. But I can't go blaming other drivers for creating the traffic, even though they're the ones keeping me from moving! It's an infrastructure matter, of course, same as the problem with the bicyclists clogging the major roads. No right to get mad at the individual who's just doing what he or she has every right to do.
