I believe it. Traffic behind might had been moving very fast and some jerk decided to punch it at 80 mph and came up on slow moving traffic cause there was cop in the left lane going at or just below the speed limit. Dude could not stop and didn't want to rear end the car behind the cop car and went to the shoulder and lost it, once on the grass at 90 mph he lost steering-control and flip.
Should had rear ended that car. Sometimes the best thing you can do is hit another car.
This happens alot with deer, people crash their car trying not to hit that poor deer and end up killing themselves.
