I had two episodes with deer.
One in December during the Christmas shopping rush. I saw him on the shoulder of a highway in an area, where one would never expect to see a deer. Very metropolitan area. I thought that if he ran out, there would be a multiple car crash, so I slowed my van, and hugged two lanes, to slow traffic.
The jerk ran right into the side of my van, hitting the front right fender, and door. He bounced off and ran back to the shoulder. The repairs went through comprehension insurance with only $100 deductible.
About 20 years later, my Crown Vic was about ten years old, and the headlight lenses were getting a little cloudy. Fortunately, a deer ran right in front of me very near my home, and I was doing less than 40MPH. I probably hit him doing 10, but it cracked one of the lenses, and my front grill.
For $100 deductible, I go two new lenses, and a shiny new grill.
Overall, there are more deer in my area, over the past ten years, and I think they are learning how to cross the street.
