Car Throttle has another great video out. This time they're showcasing the trend or rolling coal, when one disables any clean burning engine programs in a diesel power vehicle. It's a way of visibly and deliberately polluting the air just so a driver can make his ride look more like a beast (while also pissing off pedestrians and cyclists). Watch this video and see just how crazy some people go with their exhaust outputs!
