Maybe not in Banbury, but down this part of rural Oxfordshire, I know several people who drive home when they are incapable of walking to their cars! My wife insists on collecting me from the local these days as she is worried about me accepting a lift from a well-meaning but paralytic neighbour.
One local farmer, who shall remain nameless, but anyone around here would know who I mean, used to turn up at the pub in his Landy, leave the door open and the engine running, come in and have a couple of large vodkas in a half pint glass topped up with cider, neck it, then either have another or drive to the next pub. Lovely bloke, but you wouldn't want to be on the same road as him!
He stopped doing that after the inevitable ban, uses a bicycle now.
