It's final proof (if any more were needed

) that the real reason cameras exist is purely to raise money. The proposed ban on radar detectors (while leaving GPS systems alone) is tantamount to an official acknowledgement that this is the case.
If the real purpose of speed cameras is to ensure that motorists are driving within the correct limits then what is the problem with a driver knowing in advance where a camera is. That way they can make sure that they are travelling within the posted speed limit well in advance. Objective achieved.
Instead of legislating against radar detectors, the government should be actively encouraging drivers to have them as a socially responsible thing to do. After all radar detectors are a more cost effective alternative to GPS systems so more drivers can afford them.
These systems do exactly the same thing, they just work in different ways. They both give advance warning of the camera location so there is no last minute braking.
What annoys me is the hypocracy of the crude assumption that GPS Alert systems are OK but radar detectors should be illegal because drivers use them to test which cameras are not working so they can speed past them with impunity. That has to be the most illogical leap of faith they have managed to conjure up yet. Where on earth is the proof behind this ridiculous assumption?
But if they keep repeating the lie often enough people will believe it.
The real reason why the DoT view radar detectors as a threat is simple. GPS systems do not warn of mobile speed traps - lasers or radar guns. People keep forgetting to update the GPS database so new Gatsos catch them out.
Make radar detectors illegal and it becomes much easier and cheaper for safety camera partnerships to make mobile traps the largest revenue generator. Hand held radar guns only cost about £250 each compared to to the 10's of thousands for a laser gun. No GPS system can detect a hand held radar yet radar detectors pick them up over a mile away. The police already have lots of radar guns just stting around.
If radar detectors do become illegal (and at least it will take more than a year to introduce any new bill) watch out for a rash of mobile speed traps soon after!!!
