He headbutted the windshield. Seriously.
We've brought you a lot of crazy road rage videos over the years, but this may be one of the nuttiest. The incident took place in Taiwan and involved a really pissed off SUV driver. What pissed him off can't be discerned from the dash cam footage. If anything, it looks as if the road rager was driving like a maniac and looking to start beef. Regardless, he decides to stop on the highway to make life hell for the poor guy driving behind him.
Over the course of two minutes this maniac punches and headbutts the front windshield, rips off the wiper blades and beats the hood with a club. Did anyone tell this guy Mad Max already finished filming?
