there is something wrong with this video, bits have been edited the car rotates 180degrees to face the camera vehicle in one or two frames of film then a few seconds later the driver appears to be hanging out of the windscreen then again a frame later he's back inside the car could be a glitch on the camera some cheaper cameras skip frames but it seems a bit weird there is clearly a driver and a passenger, i actually think its the driver who climbs out at the end but there is no sign of a second person at 20sec just before the second impact, you can actually seen the road through the window but no 2nd person?
may have been thrown in the first impact.
he may have gotten out of the car but he'd received a pretty hard blow to the head by the looks of it so could still have been very badly injured
