Apparently he'd asked his boss if he could take the car from the forecourt, and was told no. Then he went and took it anyway, so with any luck, he's lost his job as well.
Not sure about a life ban, but two or three years would have been sufficient. A colleague of mine was banned for a year for being over the drink-drive limit. He hadn't caused any accidents or anything, but it really hit home. Suddenly he couldn't drive his son to visit his grandparents, and couldn't get to his beloved band rehearsals quite so easily. It changed him, because I never saw him drink at all after that if he was driving. Indeed, he said himself, that his ban was a fair one, and that actually, he'd got off pretty lightly.
