We've all heard about how connected and self-driving cars from Google, BMW and others are going to change our lives, but how? Audi wants to find out with its Urban Future Award, a four-city, multidisciplinary competition. Each team has a different quest, but all center around the ways that connected cars -- like Audi's "Piloted Driving" model -- can make city transportation better. For example, a Boston group will see if vehicles can take up less space using self-parking features, while in Seoul, researchers will help connected commuters socialize over in-dash displays. The Berlin team will bridge private and public transit for more efficient commuting and, finally, Mexico City's crew will crowdsource traffic data to reduce the city's notorious congestion. Audi will update each project regularly in its blog, with the best plan taking a $140,000 prize.
