So yeah I was on my way to an Army interview early this morning when the road was clear no traffic in front of me, one car up my arse behind of me. Coming down the hill which is a 30 road I was doing roughly 30-34mph to make up time and since it was a clear road (no residential buildings or built up place) and I noticed a cop walking on the pavement (PCSO Blue ribboned cap) on my side of the road didn't look like he was holding anything he was just walking through. When I left from under the bridge there was a cop van similer to this (Didn't get a good look, think it was cop)
(I think it had more windows going back on it though?)
parked on the right hand side of the road in what seemed to be a drive way as shown
Now I am not one for dangerous speed and I admit I was doing roughly 35mph. Could this possibly be a mobile speed camera? if it is any help the van was pointed front end out of where the circled area is as if it was reverse parked in to the drive.
