Some BCs cant handle K230UB, jerk 2 much... juz like some cant
handle the B9s, if you juz step on accelerator and hold it[for B9],
it will auto change gear smoothly and then release the accelerator,
let the bus glide along until speed drops, sv14 pro BCs n certain
sv196 BCs do this along Nicoll Highway, damn shiok ride!
i'm not sure if they made any modifications for the later
batches of the KUB...but one of the service 86 driver mentioned
that one of the reasons for the 'jerking' was due to the driver's
seat being bolted and being unable to adjust (to push it front or
backwards depending on the driver's different height). With that,
some drivers (more notably the shorter ones) are not able to have a
comfortable posture and reach to the brake pedal.
not sure though if anything has been done about it.
