I actually did this two years ago (not from the vehicle though). My son and I were hunting and nothing came close enough to the stand for a shot. We had left the property we were hunting and were heading home with about 15 minutes of legal shooting time left. I was driving down the gravel road and looked to my right to see a nice doe in the middle of the field off to the right. I stopped the truck, and she just stood there. I got out, took my ML out of its case, capped it, walked through the ditch, and went on the other side of the fence, and shot her. The field happened to be part of the farm we had permission to hunt. She ran about 40 yards to the woods and fell. I drove back there and we dressed her by headlights and called it a night.
