Sure, like many of us, I've known about banger racing in all its various forms and guises for years. But I don't think I ever really considered that there may be banger stunt driving. Stunts like driving over ramps to leap rows of cars — some serious Evel Knievel shit. And in a van, even.
The existence of banger jumps suggests amateurs or nearly-so people doing this, which makes sense, since how else would you learn how to do this stuff?
That also means it probably doesn't always turn out so hot.
