No, theres only one so far, unless they've added more. Be very carefull on the motorways or snake pass. The yellow cameras on gantries, looking toward you look like cctv, but are infact speed cameras, there will be another one further down the road and it measures your average speed. It's no use slowing down and then speeding up, because it measures your speed inbetween the cameras. Also there can be several in a row, and can measure your average speed over miles. obviouslly they read your registration. Recently ones on the M6 were blinded by fog. Since this they seem to have fitted lights near to were the camera is pointing, maybe this fixes it. The forward facing ones which are popular in leicester do take a picture but I don't think they are clear enough to see in the car.
What I don't get is if they can have forward facing cameras, why do they need a rear camera to take the registration and a forward camera to take the person, why cant they both be took from the front. Only thing I can think of is that the forward facing ones are by a different company and the rear facing company cant use that technolgy.
