First ask pax for any prefer road, if not, suggest a road to
pax, or even a few options to let pax decide, then whack it,
careless ECP, KPE, CTE
or bartley CTE SLE, or ECP
TPE, or tampines ave 10 TPE SLE.
Travelling cross journey from SE to NW or SW to NE and vice visa
have a lots of options, it is actually longer than direct west to
east and north to south, there is no perfect road, timming and
junctions do play a part, and like us, the mentality of most pax is
as long as no jam and too many junctions, that road will be much
preferred.
