Back in the old days in the rural south, the horse knew the way home, even with a passed-out rider.

Not that that ever happened to any of MY family, mind you....

If he had passed out while the buggy was moving the horse would have most likely taken him home.Most horses are trained to never move forward when stopped,until cued to do so-for obvious safety reasons.
