Oct.5 (GMM) A visibly upset Lewis Hamilton has threatened to quit formula one as stewards consider penalising him for driving erratically behind the safety car a week ago in Japan.

The championship leader, who could secure the drivers' title in China this weekend if he wins, says he has been made out on several occasions during his rookie season to appear like the "bad person" of F1.

"I don't think I put a foot wrong ... but no doubt I'm going to be punished for something," the Briton told reporters, amid reports that on Friday he was interviewed by stewards for the second time.

McLaren boss Ron Dennis, however, clarified that the team has not received "any formal communication from the stewards (that) they wish to see him."

Hamilton, 22, added: "It's just a shame for the sport and if this is the way it's going to keep going then it's probably not somewhere I really want to be."

He insists that the wide line depicted in the YouTube clip was not out of the ordinary, and criticised Australia's Mark Webber for following him too closely, leading to the collision with Sebastian Vettel.

"He's allowed five car lengths behind me, I don't know why he was so close," Hamilton said.

In an official statement, Webber - although highly critical of Hamilton in the FIA press conference - denied that he made an "official complaint" about the championship leader.
