Road Tax may have been reduced by 15% from 1/7, but there's no relief for motorists in Singapore as there are extensive ERP increased in the Central Business District (CBD). As expected, many motorist are now complaining and feeling that they don't a choice but to prepare to pay more.
Here's a suggestion for everyone; don't drive!
I think everyone will agree that a car is not that necessary in Singapore, so instead of trying to find ways and means to avoid the ERP, just dump the car! That’s one option that's too painful (or too 'no-face') for motorists but that's there best option. Even if you can find a way to avoid the ERP, chances are that it will be a longer route than usual, and thus that's more petrol costs. That's not even counting the introduction of even more ERP gantries in November!
So what's the best way to save money? Take the bus.
