Our complainer from the past, "Slug" says they went to the PACT meeting to complain about some car on the pavement. Apparently the Police actually need to see someone obstructed before the vehicle is causing an obstruction.
This is a useful fact to know. From now on, whenever we park our car on the pavement -such as here BS51VDX does on a build-out by Cotham Brow, we shall wait for some family to get a push-chair past, and get a photograph of them as they pass.
With such a photograph, we can demonstrate that our parking did not cause any obstruction, hence is ineligible for any penalty.
