I found another advantage to driving an ultra-low Cd car

Remember its best to just hit the damn thangs IF you can't stop. Its not worth flipping your favorite car on the freeway ;-)

You could, alternatively, move to GA.. The deer are about the size of large dogs, from what I can recall.

Ironically, the animal that I've most often heard of being hit is armadillos. The ironic part is that they're seldom hit on the road. People swerve off the road to hit them.

An ultrasonic device works on wild animals much the same way that a dog whistle works on dogs. It produces a sound that hurts their ears, or just plain frightens them depending on the species, and thus they stay away from it. As for why they don't avoid the sound of the car engine, there are no natural predators that sound like cars, while there are natural phenomena, such as flowing water, do sound similar to cars, so animals have no instinctive fear for the sound of a car. Make your car sound like a roaring mountain lion and then they'll stay away from it.

The whistles, don't work. Most of the time it's because of in correct mounting, but even mounted correctly they clog or break easily. An electronic ultrasonic device is much more effective. They make them to deter dogs from attacking, you should be able to find some that will work on other wildlife. But being aware of their presence and being able to stop is better. And since it actually fits in with the hypermiling driving tips you may want to look into the smith system of advanced defensive driving. In a previous job I was a bus driver and that was part of our safety program. Short story of it is: keep enough open space around you to be able to avoid problems by maneuvering gently, with a good 15 second lead time on your down range awareness.
