This year, French tire giant Michelin (yes, the Michelin that made the tires on your car) held its 10th Challenge Bibendum event, this time in Rio de Janeiro. If you've never heard of this thing, don't kick yourself, but for some time now Michelin has taken the role of rallying key players in sustainable mobility. This year's Challenge Bibendum was a heaping helping of cutting edge technology, concept cars, and perspectives from around the globe. This slideshow gives a taste of things to come.
