Easy is not an argument here. As Americans are too lazy to drive manuals, the use of the U.S. customary units is the only challenge which keeps them from becoming brain-dead.
Don't know why the Liberians and Myanmarians need an extra challenge. Seeing the news I think Myanmar is about to embrace the metric system.
My apologies to anyone who felt insulted by this post. It was meant to be a joke, not an insult.
