My mother lived in Iowa and she had alot of experience with hitting deer. The first event happened after she got a brand new car. She told me to remember that there are always two and you will usually hit the second deer.
My girlfriend hit a deer and she had just had her car repaired and we were coming home from the mall when a deer ran in front of us and as she braked, she hit it and the second deer.
Hubby has always had VW diesels. He now has a 97 TDI. Nice quiet engine. Never had a deer run in front of the clattery ones. They always looked at us and ran the other way. Had a buck leap right into the front of the hood on the newer one.
