If bikes want to share road space with motor vehicles, they should be required to buy licenses, insurance, and have on-board cameras that record in 360 degrees. That way bike riders who cause an accident will share responsibility for their actions.
I know the type you are talking about and even in conservative TN where I live I see them. They are rude and obnoxious. My point was though that not all riders are that way. We enjoy the exercise and outdoors. I typically ride alone on off-road trails but if I am on one of my back country roads I always am respectful of vehicles. Oh, and I mount a GoPro and a .38 revolver on my bike when I ride. :-)
