I think you'd just have to take it on the chin if you get a fine mate, 'I was travelling 22mph over the limit to overtake' might just get you a bigger fine if you contest it.
The letter of the law is that you can only exceed the limit for the road if you have blue flashers on and a whirr whirr siren going, no exceptions. The limit is from sign to sign so no slowing down time and no accelerating time. A mate of mine got done 2 weeks ago going from a 40 to a 30, hit the brakes as he passed the sign and got flashed straight away, should have been at 30 or under as he passed the 30 sign.
There are a lot of myths about cameras some with more truth than others but basically (if working) they record your reg and speed (do they really use film in this day and age?) send the info to a computer which issues a penalty notice, computers don't have the ability to think some offences are more serious than others its all just '1' or '0'.
Some people may challenge and win, they get away with not paying the £100 fine by taking time off work to argue and costing them double the fine in lost earnings.
Don't get me wrong I have a heavy right foot but if I get caught I know the risk and I will pay the penalty, I didn't just buy a 2.2 because I liked colour.
When I hear people say cameras are just money making scams it pisses me off because if you don't break the law you will never have to pay, fuel costs, road tax and insurance on the other hand.....
