it's daft, isn't it? "Ambulances Only", as per the photo on Tom's other post, says "Ambulances Only" and means "Ambulances Only". It does NOT mean "Ambulances, oh, and disabled people, and people who are only going to be five minutes, and people who are in a hurry..." Just like "blue badge holders only", it doesn't mean "...and those who are temporarily incapacitated, or feeling a bit off and don't want to walk that far, and people who've got stuff to carry, and parents with young children..." it means those who are displaying a blue badge. Nor, as you say, does it mean policemen waiting for a job. Everyone is convinced that their reason for breaking rules is a good and valid one. So far I've seen one comment about a life-and-death emergency where, yes, any and all rules go utterly out of the window. Apart from situations like that, it's just laziness and being inconsiderate.
