"It was later established that the bus had run out of diesel."

Sounds like the fuel gauge was broken, if it was only "later"
established.

Just like a Pious, then. Half decent fuel consumption in start stop town
traffic, but far worse than a conventional vehicle at near steady speed
motorway, etc, work.

And a London bus sends how much time running on Motorways, normally?
