It's called “The Green Hell,” people. Figure it out.
If watching nearly nine minutes of spinouts and cars slamming into barriers teaches you anything, it is that racing (or even just driving fast) is not as easy as it looks. It is also important to remember that this footage is just from 2014, and obviously isn't even all of the crashes that took place at the Nordschleife. Perhaps some of the most entertaining parts of the video are when you see cars which seem completely out of place on a race track.
It might not be surprising to see some of these cars crash, but it does confirm that the world still makes sense sometimes.
