Bicyclists

I have to vent my frustration because this may be one of my biggest pet peeves! And please note that I also ride a bike around town. So today I am approaching a red light and there is a bicyclist in front of me on the road. First off, I think bicyclists should be allowed on the road, BUT they should have to follow the rules of the road! The guy in front of me on the bicycle just ran the red light! IF YOU ARE GOING TO RIDE ON THE ROAD PLEASE FOLLOW THE TRAFFIC LAWS! I also have no problem with bicyclists riding on the sidewalk as long as they don't go 50 mph past the pedestrians. I almost got ran over once because I never saw the crazy speeding sidewalk riding bicyclist coming. GRRR! Sorry about the rant, I just felt it needed to be addressed!
