Ooooo. I actually saw it happen once. It was a miracle of good luck timing on my part to be in the right place/right time and looking (the bad luck was all on their part...). Driving the freeway from LA to San Diego (805?) on business with 3 other guys back around 2000. Up in front of us a couple hundred yards in another lane is a beaten old Ford Ranger driving along. Nothing special. Suddenly I watch the front of the driveshaft separate from the tranny, drop and catch a crack in the freeway. The ***** end of that truck pole vaulted a good 6' in the air, the driveshaft flipped backwards under the bumper, they waggled around a lot, and small metal parts flew everywhere. I just happened to be looking up at the time and saw the entire thing take place, but nobody else in the car did until the worst was past. It was amazing to watch. They swerved a bit and then coasted over to the shoulder. Impressed that they didn't lose it or really flip/roll. One of the coolest things I ever saw, even though those guys surely didn't think so... I don't think I'll ever have the luck of timing like that the rest of my life. 2 seconds either way and I would have been going "what happened?" I'm sure they had to replace the seats along with the driveshaft...:laughing:
