To be exact, the geometry of a moose makes it so that a lower-built vehicle will hit it in the legs, knock it over, and cause it to land on the hood, and quite possibly on the people in the front seat. This is in addition to the deceleration from hitting a critter that can weigh more than 500kg. Best result, if you managed to brake before hitting it, is a completely shattered windshield and deformed vehicle hood before the moose gets up and flees back into the bush. Worst result . . . well, I grew up in moose country, and the uncle of one of my elementary school classmates died in a moose collision.
