You've got to check out this video of an example of road rage that has gone viral after being posted on Youtube yesterday (4/2). You've got to give the other driver some credit for keeping his cool by not responding to the other enraged driver.

From the look of things in the video the driver who remains in the car apparently rear-ended the crazy guy. The guy who was hit jumps out of his car and goes crazy trying to get the other guy to get out of the car so he can fight him.

Both girlfriends stay in the vehicles - one videos the whole incident on her cell phone.

Beware of the language in the video!
