So luke,
this could be the issue you are thinking,
not sure about the wheels,
but will get him to check with satnav just to make sure,
but could it also be that the speed camera needs to be calibrated?
I have heard this can be an issue too.
Tony, yes it was at exactly the same place looking at the letters again,
obviously with the junctions reversed on the return, but exactly the same speed.
Well, he will send of the required documents anyway,
as there doesn't seem to be a way to appeal this without sending,
as I have read from other threads. Oh hum!
Many thanks.
