> Objectively there’s no advantage to either way of doing it

Objectively, there is. Most people are dominant in one eye over the other, corresponding to their handedness. Right-handed people usually have dominance in their right eye, left-handed people usually have dominance in their left eye. The dominance is manifested in better focus, better distance estimation, and quicker perception. It is to the driver’s safety advantage to have the dominant eye on the side where opposing traffic goes by.

Driving on the left side of the road, with the steering wheel on the right side of the car, places people with right-dominated vision at a safety advantage. Because more people have right-dominated vision, this makes it overall the more safe method.
