To each his own since I prefer a one on one with the deer and don't hunt anywhere that you need to have a drive. IMHO If a guy knows what he's doing it's not unethical to shoot at a deer trotting at close range, but I can't see it at full speed or at any distance. That's just me since I prefer to hunt where I have scouted and know the deer movements such that a good standing shot is presented 100% of the time when one comes along unaware I'm waiting in ambush.
