got this emAil today,anyone know if its on the level Subject: M7 Speeding fines All M7 users The M7 have implemented speed prevention devices based on the time one enters the motorway to time exiting. Based on the distance, time travelled and time started and finished, they can work out your average speed. If it is more than 15% over the speed limit, a fine will be presented. The NSW Labour Government have authorised this to be legal and that NO 'SPEED CAMERA WARNING SIGNS' are required as there are no actual radars. It is based on mathematics. So beware, your trip might cost you a lot more. P.S. If you don't have an etag, the cameras still get your numberplate! W Kerr BKG Projects and Road Engineers
