Here is the thing about tires: You need to secure them before the car can drive away. Qute the concept, aye? When Mark Webber pulled into the pits for what was supposed to be a routine tire change, his crew had a tough time completing the task at hand.

Webber drove off with the tire not entirely connected. As soon as he began to leave, the tire, of course, came rolling off at a high speed. After a couple other people in the pits avoided the tire, it ended up colliding with one unlucky cameraman, completely clobbering him and knocking him to the ground. Word is that he suffered a concussion, a busted shoulder and some broken ribs. And as bad as it is, and as much as we hope he recovers, the video is still painfully funny. Watch above.
