I have to say that despite being frustrated at not being able to exchange my American (New Mexico) driver's license for a Swedish one, I really DO understand the reasoning, since when I took my license in New Mexico, you didn't even have to be literate to take the written test (somebody would read you the questions), the questions were about 20 true-false questions, incredibly simple, and the driving test was a simple, once around the block, no problems with traffic, type of driving test, which pretty much a chimpanzee could have passed, provided it could have reached the pedals. Might be a few of the reasons why New Mexico has some of the highest accident rates in the nation per capita, don't know, but I sure wouldn't say that my NM license was necessarily the sign of a competent driver. Of course before that, I had one from Washington, D.C., Oregon and Virginia, and those were a bit harder to get.
