I think they're just not bright enough to realize they don't have to outrun the car.
One time, on a slippery, snowy road, I actually missed a deer by using the Nascar Rule of Avoiding Wrecks. I aimed *for* the deer, and by the time I got there he had managed to jump out of the way.
How do you feel about horses?
Not sure those are much smarter than deer.
I admire deer, though, in spite of my desire to eat the things.
The sound of snow, yes!
hehehehe...I'm gonna remember that rule. May come in handy some day!
