vibrating chassis, rattling metal poles etc... i still can
tolerate. but what i can't tolerate is bad aircon.
yes, i prefer the kubs more (bitch please) compared to the
citaros. come on, on a hot and sunny day, the first thing i get
onto the bus is to turn the aircon outlet for a refreshing blast of
cool air to cool my sweaty body down. the kubs have good aircon
(you have got to give credit for that) while the citaros... i can't
even find any aircon outlet and every time i took a citaro, it
feels stuffy (even at night) and sometimes it worsens when the
passenger load is higher (more ppl, more body heat).
and of course, the standing area for kubs is larger than citaros
and the kubs can squeeze more ppl than the citaros. that's why i
prefer kubs.
*yea i know some will deem this as heresy but whatever. bitch
please*
True that, the aircon on KUBs is definitely much better than the
Citaros.
The one on Citaros are like blowing towards the
top of the window, like anyone would sit that close to the window
edge. 
But sometimes i wonder is it some kind of manufacturer
restriction that they can't cut more holes into the existing panels
for more A/C vents? Or they just don't want to touch the CBU
interior of the Citaro? Cause i presume they should have received
quite a number of complaints about the lack of aircon in
Citaros.
