Title-chasing Hamilton throws more doubt over his future in F1
Lewis Hamilton roared to glory at the British Grand Prix - and then cast his future into doubt by dropping another hint that he could walk away from Formula One at the end of the season.
Hamilton, who toasted his fourth consecutive victory on home soil by performing his now customary crowd-surfing celebration with his army of British supporters at Silverstone, has moved to within one point of Sebastian Vettel in the race for the title.
The 19-point swing leaves him back on track to become the first Briton to win four World titles, and one which may be his last.
Hamilton has 18 months to run on his Mercedes deal. But fresh from equalling fellow Briton and two-time World champion Jim Clark with five victories on home soil, he did little to allay fears this could prove to be his final hurrah.
"I really can't say what is going to happen six months from now," said Hamilton. "What I do know is that I am loving racing.
"I really feel within myself that I am driving better than I have ever driven. Right now I know I am at my best and I want to stay there."
Hamilton, 32 and now in his 11th campaign, was pushed on whether his remarks meant he might not be on the grid next year.
"In life you don't know what is going to happen," he replied. "Right now I love driving, but you can't say what frame of mind I will be in come Christmas time."
Mercedes boss Toto Wolff insists Hamilton will see out his contract. He said: "Lewis is a Ferrari fan, we all are, and it's a team every driver dreams to drive in.
"We have a contract, so all the talk outside has zero relevance for me."
