All you good people who are coming over here to "try the other side of the road", just post to say when when you are coming.

I'll take the train that day.

PS : We Brits have the same situation to handle when we visit the US, of course. But we have a third combination, when we drive our own, British-configured cars over to France. In that situation you are even more likely to make an error, for while the rules are reversed your car is not.

** - Just kidding about the train bit. Have a good time over here and drive safely.
