Bicycles
You know what makes me mad? People who ride bicycles. Not all of course, but the ones who "share the road". I'll explain. If you are riding a bike on the road like you are supposed to, you are to follow the rules of the road right? Right. But unfortunately, I have seen very, very few people on bikes who actually do this. They don't stop at lights, stop signs, for pedestrians, anything. What drives me completely up the wall is the dude (be it a male or female dude) on the bike who at a red light will pass all the cars and make his way up to the front of the light, and sometimes even run the light. So now I've had to go around bike guy once, which I don't mind at all. If he's riding safely and I can pass him safely, great. If though, I pass him, stop at a light, and then he passes me because he doesn't feel like stopping for the light, and then I have to pass him again, then I'm mad. I've passed the same person on a bike 4 times on one stretch of road. So frustrating. So for those of you who ride bikes, especially for exercise or environmental reasons, more power to you. For those of you who I have to pass time and time again because you are picking and choosing which laws you follow and which you don't, to you I say grrrrrrrrrr. If you are one and the same, sorry, but grrrrrrrr will apply to you too.
