Besides being illegal in just about every state I know of.... the biggest thing is... it's just down right dangerous. You have no idea who's around, who's sitting in the hedgerow behind the animal or anything. I had one of the scariest incidents involving just such a senerio many years ago. I had returned from 2 tours of dodging bullets in Vietnam. I left the service and was living in Georgia. I had this woods that was great and secluded except for a dirt road down one side of it. One particular morning I was hunting about 125 yards off the road in a pine head. It was a big open set of pines with a thicket down one side and at the back. I was sitting near the intersection of the two thickets in the back corner. I was glassing and saw some does come across the road walking in my direction. I wasn't looking for doe meat that day so just relaxed and watched the parade of 8 does. They were maybe 50 yards out in front of me when this pickup came up the road. It was all up hill from the road to this little knob I was on. Big Bubba and Yahoo # 2 see the deer. Their first shot out the drivers window missed it's mark and took the bark off a tree about 3 yards from me at head height. My instant reaction was a round over the pickup which got it moving real fast. They could have just as well hit me as the tree. They didn't see me or know I was there. I had walked in from a logging road 200 yards away. They weren't thinking about someone being around. All they were trying to do was break the law and poach a deer. No deer is worth disregarding the old rule of "being sure of your target and what's beyond". If they had wounded or killed me they probably wouldn't have known it and would have driven off.
