Road rage can be a pretty serious problem, and this might be the craziest clip of someone raging out on another driver that we have seen.

People in Australia take their driving really serious. We have never seen someone take road rage to this level.  What pushed this man over the edge like this?

It seems like he is going to hurt himself just as mush as the driver. A human fist shouldn't be able to punch through a windshield like that.
