A triumphant Lewis Hamilton has already set his sights on winning a fifth Formula One world championship after being crowned Britain's most successful motor racing driver ever. Hamilton, 32, surpassed Sir Jackie Stewart to become the first Briton to win more than three championships, and joined Michael Schumacher, Juan Manuel Fangio, Alain Prost and Sebastian Vettel as just the fifth to have won four or more after a chaotic race in Mexico on Sunday. The Englishman finished only ninth — the lowest position of his championship-winning season — following a stunning opening-lap collision with Vettel. "Four is a great number, but I want number five now," Hamilton said with a telling grin.
