The claimed superior capacity of a bendy over a double decker has
always been hard to believe though. One gets the impression that it's
done by dividing the volume of the bus by the average volume of a
person, regardless of whether the space can actually be used (and the
same on the 378s, Jubilee trains etc).

When they call for volunteers to test bus capacity, they probably take care
to stand outside a students union bar at kicking out time. Trial runs are
probably carried out first using either an original mini or a GPO telephone
box...
