I would not have an objection to your comment
about pedestrian crossing but your argument would seem to be
predicated on the premise that only bendy buses ever leave part of
their "bulk" on a crossing. That is not my experience as all sorts of
buses can end up blocking a crossing as can other vehicles too.
There may be more instances of bendy buses doing it but it is not
necessarily just their size which is the cause. There may be a whole
load of other issues too.

The problem for long vehicles is that the law doesn't help them. If you have
two crawling lanes and a long vehicle trying to cross a zebra crossing (or
box junction), every time a car-length gap opens on the far side of the
crossing the driver has a choice - either pull forward and trail over the
crossing, or wait, in which case the car alongside him will cut diagonally
over the crossing and steal the gap. If he allows the latter to happen, it
can happen repeatedly, in which case he will be there all day waiting for a
big enough gap on the far side. Zebra crossings and box junctions should be
redesigned so that the lanes are clearly marked through them, and it should
be made an offence to change lane on a box junction or zebra crossing (with
public information films to explain why the change).
