As several have mentioned smoking.
In Queensland it is illegal to smoke in a car when children 12 years and younger are present. I think the fine is about $150 and 2 demerit points off the drivers license. Not smoking in an enclosed car with children has virtue but how unenforceable is this law ? Police have enough to do. Now they are expected to be the smoking police.
Agreed. Legislators spend way too much time thinking up ridiculous laws far too often. Seems I recall hearing that in this state, they wanted to make it illegal for adults to smoke inside their OWN HOME if minors were present. Not sure if it passed or not, but good grief! Enough is enough! LOL!
