Airbubba,
No, the Australian convention for 02/20 runways is not "lysdexic urban legend", it is policy. There's plenty of examples to prove the point, e.g. Townsville RWY 01 is actually 017 degrees. We don't seem to have the same problem in Singapore where there is an abundance of 02/20's.
My query regarding any history of incidents and/or accidents in the U.S. with common use of single digits for runways, was a query in reverse to what you may have thought it to be, if there's no problem then why doesn't the rest of the world use it as well, in the interests of simplicity. The only area that I could conceive of a problem would be at an airport with another runway ending in 6, e.g. Runway 26 at an airport also with a Runway 6.
And yes, "Taxi on the greens" in SIN does make life simpler, for pilots anyhow, it must be like working a train set up in the tower.
