Deer drives don't bother me, it's just another social event meant to put meat in the freezer. Base here does them twice a season put on by a hunt club and the shooters are Service Members, drivers are the club members.
Many here that do deer drives put emphasis on hitting the largest target (chest) of the deer and many spend the week prior to a drive at the skeet range practicing.
I see it no different then when we run rabbits with dogs, shooting at flying fowl, or running deer with dogs. You practice, practice, and practice for the type of hunting you are going to be doing. If you can only shoot at a target sitting perfectly still then we don't want you out there.
