Do you have conclusive documented evidence of this? If
not, why are you spreading such dribble on public forums?
I wish to see his evidences too - from what i remember the
Citaro's step at the second last row of seats has a "No standing on
steps". Then again, there will be people who chooses to stand at
the step.
To claim "The design at the rear is dangerous and can cause people
to fall.", it is a very big claim as not only SBS Transit
& SMRT Buses operates Citaros, there are various countries
having Citaro buses as part of their bus fleet.
