Reminds me of living to Canada ... I didn't have a problem with driving on the right side of the road for the first year or so. But, when it became normal for me and I wasn't conscious of it I got tripped up ... turned left from the left lane of a two-lane one way street onto a divided road and found myself at a red light wondering why there were cars on the other side of the intersection facing me! (Volkswagen campervans don't reverse too well at high speed!)
Problem was that driving in the left lane with a lane to my right (on that one way street) also felt natural to me and old habbits took over - I took the corner as if I was in Aus, without going through the gap in the divide!
About six months after returning to Aus a similar thing happened too me ... leaving the work carpark I turned left and thought "that car coming towards me is on the wrong side of the road" [pause] "why is HE flashing his lights at ME?" "oh, Shit, I'm on the wrong side; no I'm not, he is; no it is me!".
