One problem with airbags and animal impact is that they usually hit too high to set off the bumper sensors. We don't have moose in Arizona but the elk do a job on a vehicle. I was two vehicles behind a Chevy S-10 pickup that hit a small yearling elk. It pretty much destroyed the truck and drove the roof back about a foot. The two indian kids in the pickup were OK but covered with elk blood and glass. Bags did not deploy in that case either. Of interest; the bags should only deploy if you are going to get killed without them. If no one was killed the bags worked right. I spent some time fine tuning the bags on trucks and we don't want them to go off if you just hit a big bump off-road in the middle of nowhere. One of the other companies had their bags set too low and a big railroad crossing would set them off.
