Aww man, now that must suck for sure. That sure sounds like something an AI partner could very well do XD
For me, somethign else terrible happened....but was still funny for me.
GTA IV
Okay, trying to get to my destination, I run in front of a car by accident, as I didn't realize there was one right there. It hits me....which is fine, so I get up, only to have the car that hits me, move forward some more....hitting the car in front, and in the process, crushing me inbetween the two cars, killing me.....and it's happened twice on the game so far XD
