I used to get off my bike every 6-7 years because I was just fed up with being a nice guy and trying to teach motorists to share the road while I followed the rules of the road. I would get so frustrated I would quit cycling for a while. Then the urge would come back and I'd get right back into the saddle... 6, 7, 8 years later I'd give up again... because the animosity thrown my way by people that think they own the road would just become too much.
No, cyclists do not start out "hating" motorists, they are taught to hate. And motorists... SOME of them... what exactly is there problem... it isn't as if a cyclist is going to kill your family, or delay you so much that your dinner is cold... WTF. Enjoy your rolling couch and relax... how darn hard is it to push down a brake pedal or gas pedal anyway... sheesh.
BTW I am in a period of not commuting right now... too darn many motorists with cell phones ignoring THEIR responsibilities to drive in a proper and safe manner.
