"Lawyers in Queensland have suggested handing car keys off to sober people, or not sitting in (or sleeping in) your car while waiting for someone to pick you up, as ways of negating this issue."

So, if you suspect you are over the limit, lock your car, go to sleep on a park bench or in the gutter, get mugged, end up in hospital with your car stolen. But at least you will have satisfied the legal requirements. Far out !!
