It's a long story, landed at Luton after a 6-hour flight got to car and left parking place car felt funny pulled up before motorway and front left almost flat with screw showing. Pumped it up over pressured as 3 of the wheel locking nuts could not be removed as tyre guy broke the lock key, so ringing RAC was not going to help.
Hit the motorway and was doing 77mph to get home and entered a 50 average but never noticed the markers and there was a fixed cam on a bridge prior to hitting the first average speed pole cam as it flashed me and I don't recall Waze picking up on that one just the first average zone cam further up.
So I included a letter with the NIP explaining all this, and they wrote back saying it would have to go to court, I've looked it up, and it's a band D I think.
Funny thing is you can do 50mph in a 30 and not hit that band it goes to a band B!
Not got any points, did the A road awareness course 2 years ago for doing 47 in a 40 coming back from Manchester airport lol.
