There is no such conceptual shift as you perceive. Had that been the case, you'd not see red/yellow striped radar camera posts around. I wasn't in Doha from August 2010 to May 2011. When I returned, I found all speed and traffic light camera posts around the city painted in red/yellow stripes. Do you know speed camera are installed on stretches of road where the authorities have to "warn" the motorists that this road is "under radar surveillance". I am sure this is the case in entire Qatar.
