My point was that sometimes these decisions are made for other reasons than safety or practicality. Just as Windows OS keeps it window control on the top-right corner while macOS chooses to keep it on the top-left corner. Driving left or right seems to be more of a political decision (when Americans fought the British) just as the UI choices on Windows and macOS sometimes seem to be just to differentiate their product and make it difficult for the users to easily migrate to the other platform.
