Authorities in Singapore have announced a plan to limit the number of private cars on its streets t0 the number currently in use starting in 2018. After that date, apparently, one existing car will need to be retired from service before a new vehicle will be allowed on the roadways. There are about 600,000 vehicles on the road in the city at present.
The problem is, Singapore has no room to put any more cars. Roads already account for 12% of the total area of city-state. The number of new cars is already capped at 0.25% a year but starting next year even that minuscule number will fall to zero. Commercial vehicles and buses will still be allowed to grow at the 0.25% a year rate.
