Assuming OP's rage was directed at bicyclists, and not at motorcyclists, in which case his rage wouldn't make sense:
#1 People who rage at Bikers -:
Why the hell are people raging at bicyclists so much? All we do is cycle from A to B on our bikes. We usually choose the cycling path, but most of the time we have to cycle at the side of the road. Nothing wrong with that. Until some l bastard comes along in his huge SUV and believes the road belongs to him. The road is 45 feet wide, and there is no incoming traffic. But what does the moron do? He honks as if the world was going to end, drives past me so that there is 2 inches between my bike and his car, and then he flicks me his middle finger! What. the. forget!?
The driver thinks all bikers are scum who don't belong on his precious road. But guess what: bikers are allowed to use the road. So are horses, scooters, tractors, lorries and busses. Does the driver try to kill them everytime he drives past them? Well, he probably does. Cause he's an ignorant human being who only cares about himself.
Let's draw a stereotypical picture of the driver: It is a male, with age between 20 and 50. He is probably single, or married without kids. He has some health issues and was probably bullied at school. He doesn't like physical exercise because he cannot do it properly, due to him being overweight.
Now why is he raging at everyone? I honestly don't know. Probably because we are slower and weaker than him. Raging at other traffic contestants makes him feel good about himself. He thinks it is a good payback for every time he got bullied at school.
The brutal fact is that bikers are healtier, more enviromentally friendly and more intelligent. They exercise while getting from A to B. And they don't even hurt the enviroment!
I am both a cyclist and a driver. I know how it feels like to get raged at. But I also know how it is to drive past a cyclist in my car. And I honestly don't get why people are so upset. It's like driving past a car, only much less dangerous. It lasts for 1 second, and you don't even have to cross the line entirely (even though the law says so) to make it safe for both you and the cyclist!
