I had a fun taste of muscle memory when I moved to Japan. The car I had over there, its blinker (turn signal) lever was on the opposite side as my car in America. The window wiper level was where my American car's blinker was, though. You have no idea how many times I kept turning on the window wipers instead of the blinker. And then, when it was raining, I kept turning on the blinker instead of the wipers. It was so hard to break those habits!
And then I had to break it all over again when I moved back to America. *facepalm"
