If you have any interest about driving on the right versus left, there's an answer in the FAQ, "Why does North America drive on the right side of the road vs the British way of left?" by /u/MrDowntown .

But that reply is rather short, and if you are interested in the location of the controls in the car rather than the location of the car on the road, it only mentions briefly "Although we tend to think of a keep-left rule requiring right-hand controls, and vice versa, he points out a number of instances where curbside controls have been preferred to centerline controls."
