By Interlagos.
Well, it's all about Brazil at the moment isn't it, where sport is concerned?
Points will be close between the two Merc drivers, each one needing a win to seal the title. Rosberg will be leading the race until a gear selection issue causes him to slow dramatically for a number of laps, being passed by most of the field; Hamilton will now inherit the lead. Later, it starts raining lightly. Hamilton and several others pit to change to intermediate tyres, which hands the lead to wet weather expert Jenson Button in the much improved Mclaren, who elects to stay on slicks. Rosberg meanwhile, his gearbox issues cleared by a computer re-set, fights back to 3rd place - enough to see him champion with Hamilton still in second. Suddenly, as the commentators are congratulating the German on his impending first WDC title, the rain intensifies. Hamilton is now catching Button at a rate of knots, passing him on the line by the width of a front wing, to take the win and the championship.
Or possibly by Spa.
