I would feel badly if I didn't see roadkill deer on a very regular basis here in Kansas City where the deer are overpopulated.
Having recently hit a deer in Oklahoma while driving home from the family Christmas, and I understand what the driver went through. In the case of the Google van deer, it got up and walked away. The deer I hit needed to be euthanized, so a fellow who saw the incident stopped and we held it down to cut its throat.
The highway patrol said it's not considered an accident, so I moved on. I stopped at a rural Oklahoma convenience store nearby to get the blood off of my hands and told the clerk I had just killed a deer and left it on the shoulder of the highway by the bridge. She hopped on the phone and called a family member to go get the meat.
