Would you rather hit a moose or Australian wildlife?
Moose: mass at the top, skinny legs. Hit it at speed, it crashes through your windscreen.
Kangaroo: mass at the bottom. Hit it at speed, and it totals the front end of your car.
There are also Emus in Australia (kind of like a dangerous ostrich). Again, mass at the top and skinny legs. The problem is that if you hit one, you just break its legs and the whole bird breaks through your windscreen and lands in the passenger compartment.
Oh yeah, a friend of mine hit a cow in a 4WD with a bull-bar fitted in the middle of the night. Black cow, dark road - hit at 110km/h. Apparently the point of contact was the cow's belly, because it exploded and the car was covered in blood, guts, and excrement.
