Frightening footage of road rager breaking window

If you need any more reasons NOT to get annoyed at other motorists on the road, let this video be your final reminder. We're not sure what started this road rage incident but the way it ended is horrifying. The video shows a man standing outside the car, clearly incensed at the driver and even more upset that he is being recorded on video.

When the driver in the car asks if the guy's rant is over, the road rager punches through the window, shattering the glass.

If you can avoid engaging other drivers please do so to avoid frightening incidents like this. See the scene in the video below.
