Tried to catch it these few days in Pasir Ris interchange, but
do not seems to see it after hours of waiting.
Heard that it has gone back to ST Kinetics. This is not the
first time.
So what exactly is happening to it this time? 
I dunno, but I heard that BNDEP did not know how to maintain
this bus properly, causing it to break down oftenly(like how
SLBP maintain those demo buses due to inexperience)
