The biggest problems with bicycle riders on main roads is the inability to go at traffic speeds most of the time where I drive(i.e. Suck creek mtn.&Suck creek Rd.)Motorcyclelists do not cause the problems that bicycle riders do. In an article in the times free press someone said that "bicycles have a calming effect on traffic",the absolute opposite is true. Most people I know grit their teeth at the arrogance and disrepect the these so called "bikers" show.
