The speed limit would prevent the bus from reaching critical
velocity and hence, cause the bus to lose control and move in a
tangential path that causes it to crash through the railing and
into the bay below ( remember the time where CI loved to crash new
B744s into HK Kai Tak ) The bus may not explode on impact, but will
sink very rapidly ( Dun want to give the actual proof, but can if u
want )
If the DD is travelling in the left most lane and the truck hits
it, the probability of it flying out and into the sea is damn low.
This is because the centripetal force holding the bus to the center
is at its highest, and this coupled with the inertia of the bus,and
if its travelling fast enough, will not go into a tangential path (
ie into the sea ). Rather, the bus will tip over and fall onto the
highway, causing a series of accidents and blocking the road, as
the equilibrum of the bus is least stable cos it is tilted at an
angle while turning to provide the rather large horizontal
component that is required to bring it through the turn.
