because of the inherent design of the chassis, especially rear
engined buses and even more so for low floor buses, which require
the engine to be placed at the back requiring a higher floor. thus
it is not possible to situate an exit there.
as for mid engined buses like the Volvo B10M... i am not too
sure.
