Lewis Hamilton: Points lead 'zero comfort' in F1 2014 title battle

With his Mercedes F1 team so dominant this season, shadowing team-mate Nico Rosberg in Abu Dhabi should on paper be fairly straightforward for Hamilton.

But Hamilton says that the shadow of double points leaves him on edge, as if he retires, Rosberg can be champion by finishing fifth.

"There is zero comfort going into the next race because it's 50 points to gain and that's never happened in Formula 1 before," said Hamilton.

"It just so happens to be this season and, in the last race you never know what's going to happen. So I'm going to the last race to win."

Hamilton believed he could have won the Brazilian Grand Prix if he had not spun in the middle of the race as he pushed hard to try to get past Nico Rosberg during a pitstop window.

A triumph at Interlagos would have been enough to give him a 31-point lead heading into Abu Dhabi.

Even so, Hamilton says that he has no regrets about what happened, and will not rue the moment as decisive even if he loses the title.

"I don't think I'd made any mistakes in a race [in 2014] as far as I can remember," he said.

"That was a mistake but I'm not going to look back on it, it's done and dusted.

"I'm not leaving with any regrets. It's seven points [lost] but I still got second."
