Autobabahn is an titling sans-serif font inspired by the Japanese railway and highway signage and the American license plate lettering. Each of the letters have different widths between the capital and small letters. The name combines the German "autobahn" and Japanese "baba (gap)". Superscript lowercase letters are accesible via OpenType superscript feature. This is not the first font to have this, with the first was Sunflower Highway Sign Caps, which was a very large success to the predecessor.
