The problem is loose moose. You can run into one on a bicycle (happened to a doctor here) and it may or may not stomp you to bits. Hit one with a motorcycle and spend time in the Emergency Department. Hit one with a car or truck and you get a new vehicle and possibly get to meet folks at the hospital. Hit one with a train and you get mooseburger. In some places you can salvage the meat as a kind of pity prize for your own damages.
