Brawn GP's Jenson Button waves as he drives past the crowd in a 1938 Mercedes-Benz W154 racing car at the Goodwood Festival of Speed in southern England yesterday. The Briton, the current F1 championship leader, was joined by the likes of McLaren's Lewis Hamilton and Red Bull's Mark Webber at the West Sussex event. More than 75 of the world's leading motor racing drivers and riders were expected to figure in this year's festival which also paid tribute to Sir Frank Williams, who is celebrating his 40th year in Formula One racing this season.
