I know that I’m a little internet-late to this party but the iQ Agility Font is a really cool project. The Belgian advertising agency Happiness Brussels asked Pierre Smeets and Damien Aresta of pleaseletmedesign to create a typeface with a Toyota iQ. They collaborated with Stef van Campenhoudt, a pro race pilot, who had to drive all the characters with the iQ. Zachary Lieberman wrote a custom software to track the movements of the car and translate them into single characters. Of course you can download the font for free here. You can find some making of pictures in this Flickr set.
