An animal that size can total a small vehicle.  At least the drivers and passengers would survive.  Unlike with a moose.  Moose are so large, with such a high center of gravity that when hit on the highway they often launch over the hood and into the windshield and cabin of the car.  A highway collision with a moose is often fatal because the animal pretty much cleans off the whole vehicle above the bottom of the windshied.  Duck, or die.
