US GP: I'm not getting bored after Austin win says Sebastian Vettel

The Red Bull driver took another commanding win to become the first driver in history to win eight straight races during the same season.

Vettel has been undefeated since the Belgian GP in August.

Despite the ease with which he is winning races this year, the four-time champion insists he still has plenty to keep him busy.

"It is not as if I am getting bored," said Vettel. "I have quite a lot to do, looking at the gaps, I have to match their pace. When they come closer it is not the best feeling. you want the gap to increase always, you don't want it to become smaller.

"It was clear this weekend that we have a very, very good package, especially on the long-run pace. We might have compromised the pace yesterday, but today I was happier with the balance.

"The car was similar to Friday so I was very happy. You do tend to have quite a lot of work in the car. It is a Sunday afternoon drive but not in that regard."

The Germany said he was very proud of having added his name to the record books, and labelled his run of victories as incredible.

"It makes us very proud of that moment," he said. "I think it is very difficult for all of us to realise what it means.

"One day people might look back and talk about our time and what we have done as a team. Everybody is happy to just turn up and give it everything.

"If there is one thing, that is the secret. Yes, the car has been mostly very reliable but it is the mindset we have, trying to give it everything we have, not miss a single step.

"People tend to forget that every single weekend is a challenge on its own. To have such an incredible run is very difficult to realise."
