the logic behind being allowed to drive for a year with a us licence and then having to sit a test to get a uk licence?
Never expect logic from the government. You'll go crazy trying to find any!
It used to be that the U.K. would do a simple license exchange from places where they'd arranged a reciprocal agreement and, presumably, determined that the driving standards were sufficiently similar. The only reason we now automatically swap for any EU country is because the EU laws say we must.
Personally, I think it's grossly unfair that the government won't also grant the same license swaps to those holding U.S. licenses, and I agree with you that there's little sense in saying you can drive for a year. After that time you'll be far more familiar with British roads anyway. It wouldn't be
quite so bad if they would at least relax all the newer requirements (hazard test etc.) instead of treating you like a novice.
There are several other threads in the travel section on this subject.
5 minutes later I walked back into the office and asked the guy, "how do you get it into reverse?"
Reminds me of the time I borrowed a Volvo a good few years ago. It was the first time I'd ever driven one, and I sat there for a couple of minutes trying to figure out how to shift into reverse. I tried the usual lift up and push down on the knob which you need to do on some units, but it just wouldn't go in. It was quite by accident while fiddling with it that I suddenly realized that the plastic collar around the lower part of the stick wasn't just decorative but slid upward and was the safety catch for reverse.
While on the subject of controls, mirror images, and so on, let's mention the switch for the turn signals. Traditionally, British cars used to have the stalk on the right side of the column, so it was up for left, down for right.
On newer cars in the U.K. market though, you can find it on either side. From my casual observations, I'd say it's mostly the European models where they've just kept the same steering column switch arrangement as for LHD Continental models, so it's on the left. Japanese models mostly seem to have it on the right -- No doubt due to RHD drive being the norm in Japan so that's their standard position anyway.
