It is pretty much down to the pace of life and high density
population (pple and cars) here in sg. Everybody is rushing, most
for the sake of rushing, because he/she is doing that in work
everyday. It's no wonder the heart attack rate among s'poreans is
high.
And it doesn't help when most of the roads are densely filled with
vehicles all the time, unless you are driving along mandai ave, lim
chu kang, loyang, etc. Esp. during peak hrs, sometimes filtering is
not easy, and it makes you look like a road hogger, even if you are
already travelling at 100 kph. Somehow the guy behind you still
thinks that you are driving a tortoise!?
