I anecdoted in the past that I was on a 21 in the Old Kent Road which,
every time it was displaying "21 to Lewisham Centre" actually
announced "Crystal Palace" (although it was correct at announcing the
stops on the approach).

I failed to anecdote at the time, that about six months ago I was
on an A10 which at some point started to consistently announce itself
as two stops ahead of its real location.

It eventually announced the same one twice to catch up a bit, but
it's still a spectacularly unhelpful failure mode!
