Okay kids, here's your lesson for the day. When you go to a motorsports event (that isn't a rally), there are these things called walls. They're big and hard. There might be stacks of tires in front of them. There are also these things called barriers, catch fences and run-off areas. They exist to protect you, the spectator, when something inevitably goes wrong on the track.
If you don't have these things, you probably shouldn't be watching whatever four-wheeled mayhem is taking place. This gentleman learned that the hard way, after getting a bit too close while some hoon drifts his BMW 3 Series.
Scroll down for the video, and be warned, while there isn't any blood that we can see, some viewers might find the sight of a human getting punted by a BMW disturbing.
