This is one of the first things I noticed on arriving in Singapore -- the ride from the airport to city I would normally expect to pay $30-40 US dollars for, and yet it consistently costs no more than SGD $15-20 (I usually just round up to 20).

Yet I understand that gas is not cheap, and car taxes are ridiculously high here.

What is the explanation? Is it a public service helping to make up for where public transport does not serve well, or to make people like Singapore even more??
