it looks like he pretty much just skinned the deer, I doubt there is much for bones in there. the rest of the deer is laying on the road somewhere.
if he would have hit the main body of the deer at 140mph there would be way more damage. Look what happens to an old pickup at 60mph, the whole grille is smashed apart, bumper probably bent.
and you KNOW the front end of an old truck can handle more impact than a new BMW
