Wait until the moose is out of your way
Imagine you get out of the mall and want to go back into your car, but you find a moose eating grass right in front of it. What would you do? Do you wait until it goes away, or do you walk up to your vehicle anyway?
As long as you don’t start your car, it doesn’t matter what you do. Even if you go in reverse, the moose could get scared and get in your way in an attempt to run away. When an animal is so big, you should better wait for it to leave.
