I work with a company that has some of these signs.

They are reasonably new to the market however some of them aren't legal or council approved. Its quiet a big effort to get them thru council, plus as we all know different councils for different regions makes it tough.

They seem to be working as some dealers in QLD are using them on a regular basis.

Therefore its not really a workaround for getting council approval, they actually make it harder.
