Warning: this clip features a lot of very bad language screamed very loudly, so you might want to turn down your speakers.
Holy crap. There are a lot of road rage videos out there but this one definitely ranks at the top in terms of most insane reaction to bad driving. We don't know a whole lot about this video but it is pretty clear that the man screaming and cursing was very worried about his child possibly being put at risk due to the man holding the camera. While I understand the concern a father has for his child, I'm not sure using your bare hand to smash a stranger's passenger window is the best way to protect that child. But oh well. I guess different people prefer different parenting techniques.
