Karl du Fresne: The Mother Grundy authorities won't rest until we're frightened to drink anything at all

I wonder if this will be the summer when I get pinged for exceeding the drink-drive limit.

It’s bound to happen sometime. Like most New Zealanders I enjoy a drink, and we’re coming into the season of Christmas parties, barbecues and leisurely outdoor lunches.

Trouble is, the tougher drink-drive laws introduced last year make it far more difficult than before to judge whether you’re over the limit.
