Me and my buddies do deer drives here in northern Ohio when we can get our schedules to match up. Usually 4-6 people. The more people the less safe it can get. Don't put standers in tree stands because they won't be able to move if they need to in order to get a shot. The drivers should move quietly and still hunt through the woods for 2 reasons. 1) The deer most likely won't be very spooked and won't be running therefore allowing for an easier shot. 2) The drivers may be given a shot opportunity as well therefore increasing the chance of someone taking a deer.
Just as in all hunting safety comes first!!! Everyone needs to know where everyone else is and where there drivers will be coming from as they move through the woods. Getting an aerial map of the woods you are driving it a good way to design an effective and safe deer drive.
Driving also works best when it is done on smaller tracks of land. The bigger the woods you are driving the more likely the deer will just run a wide circle around and you won't see them.
It may take a season or two to get a system down that works but once you do deer drives can be very successful and may help you get that big buck that sits real tight.
Hope I was some help
