Speed Cameras - should we have warning signs?

There is a radical difference in the way NSW and VIC motorists are treated by speed camera policy.

One state at least appears to cooperate and encourage their drivers to 'slow down' and obey speed limits through the use of warning signs and other messaging.

The other state prefers to hide, forego messaging, and catch drivers who break the rules. In the human mind, this creates an atmosphere of surveillance to drive compliance, and was demonstrated by the 'Panopticon' designed by Jeremy Bentham - a founding father of utilitarian ethics.
