I just went with the only number I could recall from reading.
For sure, the direct cash loss from crop damage is--as you showed--just part of the equation.
Vehicles? Hitting a fully-grown hog is like hitting a rock. If you don't center it, you can easily have a rollover. Never hit one with a front tire!
A drifting generalization: Try to go in front of a deer, since in fear they nearly always retreat to the last known place of safety. Try to go behind a cow, because cows hate to be "headed" away from a goal. Horses? Good luck. Horses are suicidal and will try to stay directly in front of you. Hogs? Hey, whatever seems righteous at the moment. Again, good luck.
