Central London is constantly dug up and rebuilt with many bus route diversions.
A trolleybus wouldn't be able to divert along an unwired road.

Many of them have a small generator or battery for precisely that purpose.

They're also a nuisance when the pickup arm gets disconnected from the wires.

It's not hard to put it back on using the ropes at the back.
