I'm inclined to exempt that kind of thing from criticism.
I don't see any great obstruction to anyone in the photos.
It looks to me like they have found a section of pavement that is wide enough to park on yet not obstruct pedestrian traffic.
The roads are our infrastructure, and so are our telephone lines.
They often share the same routes.
If a BT van has to temporarily obstruct the highway or pavement to fix our phone lines, than that's OK by me.
It's a necessary and temporary obstruction, rather than a random one.
At worst, they should have gotten a road closure order from the cooncil, and caused greater inconvenience.
But perhaps they reckoned that was overkill for the issue they had to deal with.
( If they park like that to go buy a baccon buttie, that's a different issue. )
