Hi Bro, I drove before in Taiwan and Korea. As you say the master eye looking at opposite direction is truth. Right eye may estimate distance more accurately as compared to left. Most important when making left turn, I experience before making a left, turn did not check left and make a left turn, end up a head on situation. Remember to check left side when driving on right lane country.
I'm with you ! I drive both right and left vehicles ...daily, I live in San Francisco, my own vehicle is a Toyota Alphard 1st gen, RHD only imported from Hong Kong, and my work duty is driving a 2 ton Postal truck which is LHD in United States ! Sometimes , espeically kids will point at my Alphard saying : look the steering wheel is in the " wrong " side . I just laugh .........!!!!
