one thing about the average speed cameras is... a LOT of them are fake... (or dont work?) - all the ones on the A1/M1 are fake
also, for the ones that do work, they have to have a picture of you in the same lane each time, so they cant give you a fine/points if youre in a different lane for each photo.... (guess this only works if theres enough lanes so you have 1 per camera tho ?) - some footballer was caught and hired himself an expensive solicitor who got him off because of this.... so now they have to do the same for everyone else
