The EU document linked to at the end contains a definition of the term
'double-decker articulated bus or coach', which suggests that these things
either exist or are likely to exist (or that EU lawmakers have too much
time on their hands).

Because Bendy-Buses can accommodate more people

Hang on - how does a single-decker bendy accommodate more people than a
double-decker bendy? I'd have thought the double-decker version would
accomodate roughly twice as many!

plus allow for faster loading with 3 doors instead of 1 for Entry/1 for
Exit.

Why couldn't a double-decker bendy have three doors, like a single-decker?

And why didn't TfL get the four-door Citaro G?

I think everyone who has replied has interpreted what you said as
meaning "Why not use double deckers instead of bendy buses?". The idea
of a double decker bendy bus obviously seems quite strange! Personally,
I'd like to see one, although whether I'd like to travel in it is
another matter!

Of course! I can't believe i forgot that.

Genius. Terrible film, but genius nonetheless.

I take your point. I understand that in some places, they have
double-decked trams and trains, too. Seems like an easy and general way to
increase capacity (obviously not very practical for tube lines, though).

My tongue may not have been far enough into my cheek to be visible at this

It is indeed a badly-chosen subject line, and i apologise unreservedly for
it.

I was trying to ask if there was any conflict between decks and hinges,
rather than which would win in a fight. I spent a while trying to come up
with a title along the lines of "Decks, hinges, and things that roll", but
couldn't think of anything not lame enough, so dashed that off instead.

Yes. Articulated vehicles don't just bend left to right, they bend up and
down as well. Assuming that the lower floor was of a fixed length, the upper
floor would have to be able to change length, i.e. there would need to be
something like a concertina section in the *floor* of the upper deck. The
best I can think of would be to have something like the combs used at the
end of an escalator, but because the combs would be sliding back and forth
unpredictably, I think it would be less safe than an escalator.

Hang on, there is also twisting to think of. That scuppers the combs idea,
so the only way to have a double-decker bendibus would be to have two
separate upper decks with two staircases.

Then again, if the bendibus had only four wheels - one at the front, two in
the articulation and one at the back - there would be no twisting movements
to worry about, so that resuscitates the combs idea.

I don't know what I'm talking about. I should shut up.

What about, instead of increasingly complex double decker bendy
polydimensional buses with towbars for the wheelchairs, prams, cyclists and
skateboarders to tag along behind the bus, etc, what about simply having
normal buses, but more than one of them. Say, perhaps, three - all come at
once. Wouldn't that be a functional equivalent?

Certainly double-decker trains in Switzerland. From the entry
doors you descend several steps to the lower deck or climb stairs to the
upper. Many of the S-Bahn trains around Zurich are so equipped.

And then you've got the double-decker trains that go under bits of Paris.
RTAP or RER or whatever. Why does most of the Paris metro smell like a
sewer? London's tubes don't whiff like that. I know Paris is marginally
closer to the equator (and marginally further away from the Arctic), but is
a climate difference to blame? Maybe a diet of snails, horsemeat and frogs'
legs leads to more frequent methane emissions.
