Perhaps nothing has brought such a startling advance to the human history as the wheel. Indeed, it has been wheeled vehicles of one
sort or another that have carried us along the path of progress. Whether they have one wheel or ten, our vehicles still apply the same basic principles as we continue to find new ways to make the wheels turn. Indeed, humanity will probably continue to work by turning wheels for as long as there is life upon the Earth. The automobile stands at the pinnacle of wheel technology; it is the flower of modern civilization. We, as human beings, want to keep the wheels turning, and that passion and striving are what is symbolized in the "Tokyo Motor Show Mark."
