Audi has been making luxury and sports cars for a long time. The latest mode of transport to be unveiled by Audi isn't a car, it’s an electric unicycle or monocycle in Audi speak. The device is called the A0 and was designed by German and Mexican students. The A0 is sort of like a combination of a unicycle and a Segway. It reminds me of the time when I was young that my cousin did a face plant on the road trying to ride a normal unicycle.
