22. Rolling Coal
In these environmental-cautious times when people try to protect the environment and turn to hybrids or electric cars, there are still some enthusiasts who take pride in polluting the environment. This is how the Rolling Coal movement was born. What is this exactly? Well, if you own a diesel truck you will notice that it produces a small amount of black smoke. People who wanted to show their disrespect for the nature modify their trucks to puff large amounts of black smoke by removing catalyzers or messing with the exhaust. The result is black smoke screen while revving and annoying the rest of the people on the stop lights and traffic jams.
