I hit a deer back in October of 2002.  It was an empty country road and she had plenty of time to cross before or after I got there, but oh nooooooooooo.  The little thing had to wait until I passed someone at 70mph before bounding into my lane.  The collision was pretty violent and I remember I didn't even stop to check the damage.  I just drove the rest of the way to school in this trance-like shock.
Sometimes it seems like animals time their run across the road such that they'll get hit on purpose.  I mean, what could be so pressing that they absolutely have to cross in front of a car with only seconds, or less, to spare?
