I doubt that is relevant. I also come from a country that drives on the left side of the road and feel perfectly comfortable in the left seat of an aeroplane, or the right seat, or the middle.
Interestingly enough I did have some muscle memory problems when transitioning to the left seat of a Dash 8 from the right seat, but it wasn't right seat muscle memory that was getting me, it was left seat muscle memory from a piston twin. During the upgrade sessions in the sim I would occasionally raise my right hand up to the overhead panel when I wanted to apply some elevator trim. The trim in the Aero Commander, my previous left seat aircraft, was in the ceiling.
