It's long been hard to believe people still drink and drive - how could anyone be that selfish and stupid? Especially given the damage drunk drivers have wrought on families, often destroying their own lives along with those of others.
Some of us grew up in a time when the practice wasn't as frowned on as it is today - a bit like smoking.
But you'd have to have arrived in a time machine from 1985 to not know that drinking and driving is absolutely unacceptable.
It's encouraging to see fewer locals are being caught - 570 in the year to June, down from 730 two years earlier - but that's still 11 people a week.
How do you like those odds - every time you or your loved ones head out on the road, could one of those drivers be coming the other way? And those 11 are just the ones who were caught.
