Singapore govt smarter than Malaysian govt
While the Malaysian govt can only think of building bridges to collect tolls, Singapore only needs to erect ERP gantries to do that. In the former, building bridges will take a long time and a lot of money upfront. In the later, the roads are all there and erection of gantries will cost next to nothing. And the money collection is instant. See how fast we generate revenue. And gantries can be added anywhere. In a bridge, you can't have more than one collection gate.
