A friend of father's once got arrested for being drunk, he was un able to walk when the officer nabbed him, and he asked the cop to help him to his car, as he was too drunk to walk, but he thought he could drive OK. He spent the night in town that night. The problem with allowing people to drive drunk, is that after one drinks a bit, their judgment is impaired enought that they can not tell when they go past the legal drunk limit. Any one who would drive in this fellow's condition probbly was impaired before he started to drink.
