In Malaysia, the license plates of cars vary by state just as they do in the US. Instead of state denominated plates, each state is assigned a letter of the alphabet so license plates from Penang begin with PA. The first car probably had the license plate PA 1 and on it goes until PZ 9999. Afterwards, it goes to PAA 1 and so forth.
In Kuala Lumpur. the license plates begin with W - and so now we have WTF all over the roads.
