you go lornie heading towards PIE from AMK/Braddell ... you sure
steam gao lat gao lat during morning peak 
May get invited to drink kopi if argue further..hehe
Let pax decide lah, if pax not sure, give options, TPE SLE KJE
corporation drive
or KPE PIE (tuas), TPE CTE LORNIE PIE and so on...or take
helicopter.
For long distance trip, try not to go by those serangoon many
traffic light road, pax already know it is a long distance, they
expect expressway type, given a morning peak, best is to avoid PIE,
smlj expressway, should call it Jamway
