The post on the HP doesn't speculate as to exactly why this 650S GT3 lost a wheel, and I honestly don't have any idea. Maybe there was a flubbed pit stop prior? But regardless, it's insult to injury that it managed to smack the car it had just left — immediately after the driver went into the wall. Fortunately, he's fine. Watch the video below.

 

Still wondering what caused the wheel to come off...
