Formula 1 race director Charlie Whiting says he's happy to "forgive and forget" Sebastian Vettel's Mexican Grand Prix radio outburst, in which the German told Whiting to "f**k off" twice.
Vettel escaped punishment for his language after he sought out Whiting immediately after the race to apologise and wrote a letter of apology to FIA president Jean Todt.
Whiting, who attended Thursday's drivers' press conference, insisted Vettel's apologies were sufficient and he therefore considered the matter to be closed.
"It is not the first time bad language has been used, of course," Whiting said. "The fact that it was directed at me was unfortunate, and I think there were a number of mitigating circumstances that led up to Sebastian's obvious frustration.
"But the fact that he sought me out very shortly after the race to apologise for me that was enough, and I am prepared to forget and move on. And that is really what we should do.
"Things happens in the heat of the moment, and I think you've seen what the FIA's position on this is and I personally feel that is enough."
Vettel admitted he regretted what he said over the radio and was happy to move on from the episode with Whiting's forgiveness.
"I am sorry for what I said, when you are racing and fighting, I think you can understand why I wasn't so happy at that point," he added.
"For sure I regret what I said, certainly didn't mean it. It was a very clear thing for me to look for Charlie right after. I am happy that Charlie accepted the apology and happy to move on."
