Here is a simple FACT, if your right eye is the dominant eye, it targets the object you're looking at and your left eye adjusts to focus on what the dominant right eye is looking at.
My point (without the help from Wiki) is that driving on the left hand side of the vehicle with the centreline of the road on your left, means that your right dominant eye has to focus across to the left (diagonally), which is not natural, it is like a right handed shooter aiming with his left eye.
No one has answered why during the 20's most cars switched from RHD to LHD, maybe the Yanks couldn't change gears with their left hand, even though they left the pedals the right way round, right foot (dominant if you're right handed) accelerator/ brake.
Probably Henry Ford made a blue on his production line and it was cheaper to fit the steering on the left, Regards frank.
