The numbers are large enough to give you pause about taking the ol' car out for a spin.
Prompted (presumably) by the Mike McGavick DUI admission, the Seattle Times set about considering just how many DUI cases the state of Washington has had in recent years. So: Since 2000 - in this decade so far - it has had 220,640 DUI cases. Not allowing for duplication, that's somewhere around eight out of every 100 people in the state.
But the total number of offenders isn't quite that large, of course. The Times also considered duplication, and it turns out that of the drunk drivers in those cases, more than 30,000 were charged with the offense more than once.
