I am used to driving on the right now and the van is of course lhd, but occasionally you'll find yourself having an English moment! I did the same in England the last time I was over there. I drove the wrong way round a mini island on the approach road to a supermarket in my old 1974 Rover. My mate, who was in the passenger seat said, "You're not in France now!" Fortunately there were no other cars there at the time.
