Sure you can. He was wrong about the gun rack as well but you don't have to shoot them. He hasn't driven in my neck of the woods. The Volt has a passenger seat, doesn't it? Around here, the deer come in through the windshield.
That's more of a problem with low-slung passenger cars than it is with the pickups the hunters drive. Some of our hunters put their deer tags on the front bumper, get a six-pack and hit the road. Their chances of success are very good.
