World Champion Lewis Hamilton says talks are not required with Nico Rosberg after clashing with his Mercedes teammate at the start of the US Grand Prix in Austin.
The 30-year-old secured his second consecutive world title at the weekend, partly thanks to Rosberg's error in lap 48 which gifted Hamilton the lead. And following the race, the German was spotted throwing his second place cap back at his teammate (watch below).
Had the Brit failed to win, the race for the Championship would have been extended until at least this weekend's Grand Prix in Mexico City.

"There is no need," Hamilton told BBC Sport. "Everyone has a right to an opinion, but it doesn't matter. I won the race.
"I've seen Nico in lots of different lights over the years. The cap came past me and I'm like 'no problem'. I'm completely oblivious to it, but I understand."
It is the second consecutive season Rosberg has missed out on the Drivers' title to his teammate and his emotions were made obvious immediately after the race.
The 30-year-old appeared to congratulate his teammate, before throwing his cap back at Hamilton, who had tossed it towards him initially. He was later seen to step aside in celebrations, which saw Hamilton win the third title of his career.
"These boys have known each other for 25 years and it was like throwing the cap to your mate and saying, 'time to go on the podium,'" Mercedes boss Toto Wolff told BBC Sport.
"If it were drivers from different teams, it would be seen as completely normal, what we all love to see and like it should be."
Rosberg's aggrievances may have been caused by his inability to close the gap on his teammate from last season. The German finished just 67 points short of the Brit in 2014, but with three races to go this time around, he is currently 80 points behind the champion.
Hamilton's form this season has been admirable - partly down to the consistency of the car which struggled for reliability last year. However, the former McLaren driver is likely to be favourite to win the title again next season, with Mercedes ahead of the pack in the new V6 era.
"It's the worst thing to be my team-mate. On top of everything, he was disappointed with himself," Hamilton added.
Although Wolff is happy with the relationship between Rosberg and Hamilton, the 43-year-old admitted it is important they manage the situation.
"Because there is such a huge resource in the team and so many people putting so much effort into delivering such a race car, we don't want any rift to happen between the two sides of the garages," Wolff said.
F1 heads to Mexico this weekend, followed by the Brazil Grand Prix before the season-ending race in Abu Dhabi at the end of November.
