British racing driver Jann Mardenborough, who has competed in the Formula 3 European Championship, the GP3 Series, and the GP2 Series, somewhat incredibly, spent years training for the profession by playing car racing video games.
He was a massive fan of the original PlayStation game Gran Turismo, and became so good at driving in the video game, that when he entered a GT Academy competition in 2011 (where Gran Turismo players were offered the opportunity to get started at real-life professional racing), he became its youngest ever winner at 19 years old, beating 90,000 others to the top spot.
