Yannick is facing a challenge: describing himself in 600 characters, although he is only normally allowed to use only 280 characters on Twitter. His private Twitter feed contains sports, politics and memes. His longest car ride lasted 32 hours and, contrary to expectations, did not take place in Stuttgart's Rush Hour. In this rush hour, he likes to rely on the "Yellow Lightning", as the subway of the Stuttgart public transport company is affectionately called. And yet - or for that very reason - he likes to write at Daimler about the mobility of the future.
