...e la FIA ha già detto, tramite Autosport che tutto è stato regolare e pertanto, si conferma che il mondiale lo ha vinto Vettel.
On Wednesday evening, however, Ferrari said it was reviewing video footage allegedly showing Vettel overtaking Vergne in a yellow-flag sector between Turns 3 and 4 early in the race. It stated on Thursday that it had written to the FIA asking for clarification over the matter.
FIA sources have confirmed to AUTOSPORT that the yellow-flag sector at Interlagos starts at the light panel just before Turn 3, at marshal sector 3, and ends about 150m before Turn 4, where a green light panel is displayed.
However, there is a marshal's post inbetween these two panels and a green flag was being waved here on that lap.
Under the FIA's rules for the Brazilian GP, if a green flag is displayed before a green light - as it was in Vettel's case - it is the first green that counts.
Therefore, the FIA is in no doubt that Vettel's pass was legitimate, which is why race control was not informed of any potential infringement.
