I have pulled the reciprocal action of driving in the left lane of a two lane road for awhile until an oncoming car shocks me into the realization of what I’m doing. On many freeways the left lane is much smoother because it gets used less frequently, so often times in lonely stretches of road I will cruise in the left lane. Then when I get onto a two lane road, habit takes over and I find myself driving on the wrong side.
Only happened a couple times.
