Drunk drivers average one arrest for every 27,000 miles driven while drunk

On the way to the gym this morning, I heard some disturbing news on the radio: John Knowlton, 27, of Onset, Mass., was flown by medical helicopter to Massachusetts General Hospital after he sustained serious injuries when a drunk driver, who had five previous drunk-driving arrests on his record, smashed into a car he was a passenger in, according to police.

The drive was Carlos J. Owen, 51, and he was arrested for operating under the influence of alcohol, serious bodily injury resulting; negligent operation of a motor vehicle; and leaving the scene of an accident after causing personal injury.

This raises an interesting question: how many times do you have to drive drunk to get arrested for it six times?
