Hamilton explains Instagram defence of Vettel

Lewis Hamilton has explained his reasoning for launching a defence of title rival Sebastian Vettel on social media between the Japanese and United States Grands Prix. Hamilton demanded that Formula 1 media show the German "more respect" after an on-track error cost him further ground in the title fight.

Victory at the Circuit of the Americas on Sunday will crown Hamilton world champion for a fifth time if Vettel does not follow him home in second place.

Hamilton has surged clear in the second half of the season, winning six of the last seven races as Vettel's challenge has been hamstrung by errors on the track and Ferrari pit wall.

The Briton says harmony in the paddock is as great as it has ever been and added that his defence of Vettel was payback for the German similarly backing him up in the past.

"I think if I was in the same position he would do the same thing," Hamilton said.

"As drivers, we are all members of the GPDA and I think we all need to stick together.

"The respect that we have for one another is probably the greatest it's been for many years - at least in the years I've been in Formula 1.

"I just think, ultimately, as a four-time world champion it is the most intense year that we've had.

"Every hiccup is magnified, naturally, as it is perhaps in any sport at the top. But there have been many times where I've been in the firing range and Seb's always been really respectful and supported me, so I thought it was only just to do the same."
