Seriously, please stop.
It seems like this guy wasn't having a great day already. The last straw occurs when he's caught in traffic waiting for a train to pass, but it ends up backing up over and over again, seemingly mocking all the traffic. As the driver realizes what's going on, he is not having it.
At least they didn't stick around and waste more tax-funded man-hours trying to resolve the most idiotic road rage incident we've ever heard of. If you ever find yourself in this situation and are considering calling the cops, please consider calling a therapist instead. Holy crap. If you wanna read about some more idiots interacting with cops, here's this.
Do you keep waving people in at a stop sign even though you have the right of way? Quit it. You should be predictable, not nice. Do you cut off faster drivers trying to merge? What's that all about? Here are some things dumbasses seem to forget about while driving.
