It may not be the intended purpose but I certainly does change how the world is seen by everyone using it to warp the mind's eye to how the world actually physically is.

Edit: Does it do an excellent job for navigational purposes if you are shipping from Japan to Brazil or it it only excellent for shipping from the northern hemisphere to the northern hemisphere?

    It works for any shipping lines

    The Mercator projection was designed for use in marine navigation because of its unique property of representing any course of constant bearing as a straight segment. Such a course, known as a rhumb (alternately called a rhumb line or loxodrome) is preferred in marine navigation because ships can sail in a constant compass direction.

    Perhaps if they are unaware that a 3D image of a geoid projected onto a 2D plane can cause issues, however every projection will have its own failings whether area, shape or directional (angular). Familiarity also comes into play, and i believe that is more at the root of the issue you bring up.
