Mercedes-Benz: The Tweet Fleet

Finding a car space at Christmas time is a daunting task just about anywhere in the world, so Mercedes-Benz created “The Tweet Fleet” to fix just that by tapping into the “Park Assist” feature. Mercedes-Benz Park Assist can automatically detect empty car spaces near you as you drive, so what if they could take that feature and provide it to anyone looking for a parking spot at Christmas?
Well, they did, and the Tweet Fleet was born, a fleet of new Mercedes-Benz cars travelling around Stuttgart in Germany, automatically tweeting empty car spaces with geo-tagging to ensure that anyone following can not only find out where the empty spaces are, but can get directions directly to them. All rigged together via an Arduino board and the Mercedes-Benz Park Assist feature.
