US Grand Prix: Nico Rosberg throws cap at Lewis Hamilton
Nico Rosberg throws his podium cap at Lewis Hamilton following the Englishman's world title victory in the US Grand Prix.
The German appeared annoyed when Hamilton tossed a 'second place' cap towards him, and then launched it back toward the champion.
Hamilton had pressured his Mercedes team-mate into a mistake during a frantic last 10 laps and swept by to take his 10th win of 2015 and a third world championship.
