Lewis Hamilton is storming off into the distance now, two seconds ahead of Nico Rosberg. One mistake and the Briton takes full advantage. 

Behind them, Jenson Button is enjoying some rare racing. He takes advantage of a tussle between Carlos Sainz and Daniel Ricciardo to swoop into sixth.

Racing at the front, racing at the back, racing everywhere!

Aaman Khan:, external haaaaamillttoooooon is world champion!!!! surely!!!! you beauty!!!!!!

Gareth:, external There will be a delay before the presentation after the race so that Nico can gift wrap the trophy for Lewis.

Edward O'Loughlin:, external Proof that Nico Rosberg is not even close to being world championship material, not worthy of the title of bridesmaid even.

Drama! Nico Rosberg appears to lose his rear at Turn 14 and Lewis Hamilton pounces and is into the lead. As it stands, he is going to become the 2015 world champion!

Ah, nothing Max Verstappen can do has Sebastian Vettel goes at him again down the main straight and sweeps past and into third. Up top, Nico Rosberg leads Lewis Hamilton by 1.6s.

Hold on to your hats! We are racing again and Max Verstappen shows great confidence as he holds off a hungry Sebastian Vettel. He's on for a podium here!

Ayesha Frederick:, external Flat-mates think I am going crazy listening to the race online shouting at the timing screens. This is so intense.

Jovic Sebastian:, external At this rate, the safety car might get some championship points!

Andrew Thatcher:, external No-one has noticed the good drive by Rossi in 11th.

Daniel Woodley:, external What a race this is! The best of the season by a country mile. Lewis can do this!

Jack Whiteside:, external If you could win a world championship, you'd want to win it with a memorable race like this...written in the stars. Come on Lewis!

"OK Lewis you have 10 laps remaining, keep it nice and cleaning."

The safety car is coming in on this lap. Here. We. Go.

In amongst all the drama, things are going well for McLaren. Fernando Alonso is fifth, with Jenson Button eighth. 

After all the various crashes and retirements, there are just 12 cars left on the track.

"It is a fantastic, gutsy performance from Max Verstappen.

"It's the most amount of cars dropping out for a long time."

Lewis Hamilton takes on softs, Sebastian Vettel does likewise and they are back out in second and fourth respectively.

As it stands Nico Rosberg leads from Hamilton, Max Verstappen and Vettel.

That means Hamilton will still not win the title today, he would be 66 points ahead with 75 available. He is on the fresher tyres though.

Sean Harrison:, external Got a horrible feeling Mercedes have got Hamilton's pit strategy wrong. Again.

Tom Brookes:, external Mercedes' bottling Hamilton's tyre call have cost him the race.

"This could be a lifeline for Lewis Hamilton."

Daniil Kvyat's Red Bull smacks nose first into the barrier just after Turn 19. Safety car out again, Lewis Hamilton pits...

Hang about. Nico Rosberg is a man on the move. He has already picked off Max Verstappen and now fancies a move on Sebastian Vettel...nails it! He's second.

"If I was Lewis Hamilton I would try and see if I could make it to the end of the Grand Prix.

"Hang out there and see what happens out. He does not have the pace in these tyres, so take track position and try to hang in the best you can."

Matt:, external Vettel caught Hamilton by five seconds under that virtual safety car period. The whole thing is a mess.

Hannah Lowry:, external BBC live updates for me for the USGP so very exciting and I can't even see the cars. Keep going Jenson Button.

With 15 laps to go, Sebastian Vettel is looking to get to the end of this race on his medium tyres. Lewis Hamilton, on 23 lap-old soft tyres, is 5.4s ahead. However, if that front two stays the same, Hamilton won't win the title in Austin.

Nico Rosberg is back out on softs and is out in fourth, behind Max Verstappen and Sebastian Vettel who, like Lewis Hamilton, stayed out. The virtual safety car comes in.
