Ok Im new to cycling and have always had a car. Most of my previous experience with cyclist where positive, they either stayed on the sidewalk bike path or in the bike lane. Then there are the a-holes that on a one lane road either by themselves or with a friend choose to ride in the middle of the road and give you all types of attitude when you honk the horn. Unfortunately this sounds like you. When I do pass a cyclist I do beep to let them know Im passing and usually we both give each other a little cushion out of courtesy. When people say share the road it should go bothe ways, just because you dont own a car or like them dont be a jerk about it.
