I remember seeing this video several years ago. If I remember correctly, the original video was posted at DriveCam who claim to improve risky driving behavior by predicting and preventing crashes.
The original video (which this is not) had showed all sorts of information including the G-forces during the wreck. The driver falls asleep at the wheel and ends up wrecking, he’s not wearing a seat belt and gets tossed around the car like a rag doll. Apparently this video has since been shown on TV, though I haven’t seen it myself.
