Theres the two areas when you enter the bus blocked out to put
the luggage area. Yeah, that part kinda is blocky when some
passengers stand there and refuse to move in. People have to
squeeze past to stand at the wheelchair bays.
It would be better to have euro Vs on it because there are more
seats.
Also for a euro Iv batch 1, there isnt a seat behind the
driver's side. The freq isnt that consistent for 16 in the evening
irregardless of the buses used. Haha. 
Uh i get what you mean now after you highlight that to me, the
part about the pax standing near the doors.
Guess it depends on services? The CGA-bound
services the pax quite auto usually, they just move in to the rear.
Guess they had enough of squeezing that they take their own
initiative to move in instead. 
HAHA, the freq part. Use Citaros will be slightly better for
keeping to schedule IMO, just that the time gained will be lost
again once the bus tries to load all the pax during peak into the
narrow aisle.
