I've watched this 10 times and I still don't know what happened.....

It's real. Happened (somewhat) near here. Up by Edmonton. About 5 hours (4 if you drive like me) away.

And if you guys are still curious as to what happened. That's what happens when you don't put a driveshaft loop in a high horse car. When that driveshaft comes off the transmission it basically turns the rear end into a pole vaulter. Driveshaft catches a spot in the road and SHOVES everything out the rear end just like you saw.

If you watch the video. You see the car come around. Burning tires. Then it starts hopping. That's where the driveshaft came out. It's bouncing under the car and shoving it all over the place. You can see the back wheels start to go left to right and wiggle all around as well. That's the rear end walking it's self around and sheering bolts. Then finally pop bang out comes the rear end. If you look at the underside of the car you don't see a driveshaft hanging down, cause it's still attached to the rear end sitting on the road.

The rollover at 3:20 is in my city. I was at that event. It's our local "100 foot dash". Nearest race track is 2 hours away. So the local car club puts on just a little show like that. Some very quick cars. He ran a 1.82. Not the first rollover to happen actually. It's a tight spot and there's usually one good accident a year. Here's a somewhat better view:
