Brian, you know they can't use the photograph to identify the driver, it can only be used to id the car by reg no. which is why they ask the registered keeper who was driving at the time of the pic, if you argue that it wasn't you for long enough (Usually about two or three replies) they will give up as it's too much hastle for them, they like the easy ones that just admit it and send in their money!
People automaticly think there's no way out, THERE IS!
Now, pot holes, have you noticed how cars are 'Weaving' all over the place? it's like we're all behind the 'Pace car' trying to keep the heat in our tyres!
