You know, it's interesting, I was in Germany on the Autobahn a couple years ago and they have actual wild life crossings overtop it at different intervals. Imagine an overpass that is grown over with brush and grass. I wondered at the time how effective they really were. While I never saw any deer on them, I figured that it must work at least a little bit or they'd have a lot more of these types of accidents.

All that being said, I would be really surprised if that is actually a deer. It seems like a really small opening for a deer to go through. The carcass looks really small for a deer, and, after having seen a few cars that have come into contact with deer, the damage seems pretty minor as well.

Anyway, photos are pretty gruesome.
