Lewis Hamilton leads F1's open championship

With seven different winners from the first seven races, the battle for the 2012 Formula One drivers' championship remains wide open.
All a far cry from last year, when, after yet another win for Red Bull's Sebastian Vettel in round eight of the championship in Valencia, McLaren's Lewis Hamilton threw in the towel and conceded the title to the German.
Hamilton held onto his towel after registering his first victory of the year in the Canadian Grand Prix. He needed it after jumping into the rowing lake in celebration.
