F1 champion Sebastian Vettel drives his racing car during a promotional event in the Austrian city of Graz, yesterday. Some 25,000 spectators gathered in downtown Graz to see Vettel driving his Red Bull and signing autographs. Vettel became the youngest triple champion in F1 history last week as the season wrapped up with a tumultuous Brazilian Grand Prix at Interlagos. The German became only the third driver in history to win three successive titles, equalling the feats of Juan Manuel Fangio and Michael Schumacher.
