I don't bother risking it - since those have been up I think the traffic flows better anyway! I don't bother with the M11 in the morning as between Loughton and the 406 it grinds to a halt, even before the camera's, but in the evenings I use it on the way home and since everyone has had to do 50 through it leading up the the M25, traffic has flowed much better! It used to be every night without fail it would become gridlock between bank of england and the M25 flyover, but in the last fuck knows how many months I have seen it snarl up twice - thats pretty fooking good! from the 406 to the A414 takes about 25mins since those cams have been up - used to take 40!
