Is there an operational reason why so many GRT operators open the rear ceiling vent even in the dead of winter, spring rains, or summer heat?
It seems like such a waste of energy to force the heating/cooling system to try and keep up with the exterior conditions when the vent is open (and probably doesn't help aerodynamically with fuel efficiency either). It doesn't help with passenger comfort either sitting back there in the draft, noise, and fumes.
I just wondered if there was a reason this was done (too much interiour moisture? odours?).

Everyone move to the back of the bus and we all get home faster.
