I live/drive in Australia and I've never heard of such a thing - neither location or anyone fined by this method. Do you have an example location where this is in place? Or an article describing it?

Edit: old article link as the other commenter seems to have removed theirs http://www.adelaidenow.com.au/news/south-australia/sa-police...
