Remembered two more stories:
My great-grandfather (RIP) hit a deer in his Chrysler New Yorker. Deer instantly died and its leg came right through the windshield, which very well could have impaled any of the occupants.
Also, some family friends hit a deer recently in their Volkswagen station wagon. The window shattered and the deer literally exploded into a mess of gore before entering the car . The car was completely totaled and everyone was covered in blood and literal guts. The four year old boy was so freaked out that he wet his pants and threw up.
