The reason that people from Poland and other eastern European nations can exchange their driving licence for a british one is because they are part of the EU.
Yes, which is why many people see this as being unfair. We are
forced to exchange a license from another EU country because those are the EU rules, yet the government will not enter into voluntary agreements with the various U.S. states to provide similar swaps for those with U.S. licenses. They don't even allow minor concessions.
I don't know when you took your U.K. test, but I'm assuming that it was back under the old regime the same as when I took mine. In those days the test was just a 30-minute or so practical drive followed by the examiner sitting in the car and verbally posing a half dozen Highway Code questions. I can't remember exactly how much it cost, but even allowing for inflation, it was
much cheaper than obtaining a license now. Experienced drivers from the U.S. might still have had to learn monkey tricks for the "proper" British method of steering and the obsession with overuse of the parking brake, but at least it wasn't as bad as today.
Now, we have the practical drive, the written test, and the ill-conceived and seemingly worthless hazard-perception test, which in fact probably penalizes experienced drivers. I don't know the exact fees off hand, but it's vastly more expensive than it used to be.
And for what? Would it hurt to make a least
some concessions? Maybe require people to take the written test to check for familiarity with U.K. road rules and signs, but waive the practical and hazard tests for those who are clearly experienced drivers.
The requirement to undergo the full range of tests makes even less sense when you consider that U.S. drivers can drive here for the first 12 months anyway, and with the recent rule changes has to wait at least 6 months before applying for a U.K. license even if he
wanted to get one immediately.
After somebody has been driving around 6 to 12 months, he's going to be much more familiar with British roads and driving anyway.
