Points to note:
Swinging around dangerously would only come along if the
steering is turned frequently, whether necessarily or not. If the
bus swings around dangerously in wet weather then likely its out of
control.
Bendy buses used enhanced engines of single decks. It is true
that double deckers use enhanced engines of single decks too! (from
the VO generation).
I am cutting the technical stuff here cause it would be
long.
Not really. Remember the Citaro G test? Lols. Unlike articulated
semi-trucks, bendy buses have side hydraulic cylinders that prevent
such yawing motion. The cylinders will move in relation with the
steering wheel. Once the steering wheel stops moving so will the
cylinders, therefore "locking" them. Its a hydraulic valve lock
mechanism.
As for engine fires, they are caused by fuel leakage. The batch
1 Habits and below generation of bendies, some have manufacturing
and assembly defect in their engine fuel system. The fuel pump and
fuel delivery system(in this case, its using low pressure normal
fuel injectors via a small hose) did not match up. Fuel leaked from
the gaps. Once the fuel reaches the hot exhaust pipes its turned
into vapour quickly, but fails to ignite as diesel fumes and the
fuel itself is hard to ignite. Some source is needed to start the
fire.
I myself personally would be glad to take a bendy bus than a double
deck bus. Main thing is i cant sit on most seat on the top deck of
a double deck bus as im susceptible to motion sickness, hence i
tend to sit on the lower deck.
