Ambulance was coming at the back?
Is there evidence of this on the council's full clip or anywhere?
Even if not, the keeper could still state that their stopping was a precautionary measure only..ambulance or whatever..and not necessitated by the presence of stationary vehicles: as the video shows, there was room for the driver to exit beyond the box at all times.
But your words.
Each case is different, albeit with common themes, in this case a claim that there was room beyond the box at the moment the vehicle stopped, which was for other reasons, in this case.....
