Singapore's Weird Fill-Up Rule

In an effort to placate its neighbor Malaysia, Singapore has imposed a rule that allows cars to leave the state with a 3/4 tank of gas, due to Malaysian complaints that S'pore residents were simply popping over the border and benefitting from the state-subsidized low, low fuel prices. But the crafty people of Singapore, who did a lot with no real resources but a port and some ingenuity (oh, and the caning...don't forget the caning) have figured out how mess with their gas gauges so they read 3/4-full when they're practically empty. Singapore citizens 1, Kuala Lumpur, 0.
