Why are bendy-buses not double-decker?

Why not? I've heard this said elsewhere, so i assume it's true, but what's
the problem?

Think about how such a vehicle might have to articulate in the
vertical plane when the front section reaches an incline before the
rear. A hump back bridge could be an extreme example.

Any flexible joint between the two upper deck sections would have to
accommodate far more movement than the lower deck nearer the ground.

The coach mentioned elsewhere in the thread shows it can be done but
I would think its routes are far more restricted than what a vehicle
on bus operation might encounter in its service life.
And the cost of such a vehicle built in small numbers for a few
limited routes and just a couple of operators makes building one
unviable.
