Can we afford 6.5m?
In many respects we can. But in the area of transportation, I doubt we can keep pushing further. Under the present 4.5m, we are greatly stressed. We are at the verge of erecting ERPs at every junction. What if we have 6.5m? Cannot imagine the congestion. Now our car population is about 500,000. Add another 2m people, we can expect another 200,000 cars on the road. Then what? Build another network of roads? The expressways, if we double it, may still look ok. It is the smaller roads that will choke up and get blocked out. There is no way one can drive out of the car park with 700,000 cars unless we are going to pay through our nose to get the car moving. We have MRT! Even now, if we add another 10% to the commuters, the MRT will be struggling. Forget about buses on the roads. 6.5m! Still pushing it?
