If you think about it, it's not drivers that are so mean. It's just some people. There are people out there who hate everyone else, feel the world has imposed upon them and they deserve better/more. They are just angry timebombs. It just so happens that when you are on a bike and they are in a car, it is life threatening. You run into them all the time elsewhere, it just isn't as scary. I try to calm myself down as quickly as possible and I can usually do that by feeling sorry for them. After all, how much does your life have to s*ck for it to be worth scaring/hurting a stranger?
