D@mn straight. That's the rule: Do not swerve to miss a deer - hitting the ditch is more likely to kill you, and the deer is unlikely to do more than damage the car and die (though the first one I really nailed a few years ago went high, blew half the windshield into my face, and pushed the roofline back about six inches). But you have to swerve to miss the moose, because they're both heavy and high, and sure to come through the windshield and kill you. A near-miss of a moose at night is just about the most terrifying thing you can imagine, because as you pass it at speed in a small, low car like a Legacy it looks ten or twenty feet tall. It's really a weird effect, and lots of people report it.
A friend of mine who used to have a Ferrari had a much more amusing story about one of the other guys he drove with (I can't remember whether his was another Ferrari or a Lamborghini) hitting a deer out in my neighborhood, and since the car was so low it scooped the viscera and blew it all into the passenger compartment...
