Silverstone trafficpublished at 11:40 British Summer Time 3 July 2015
Different year, same old traffic problems. It seems from Twitter that quite a few of you are still struggling to get into Silverstone, and you're not best pleased.
Darren Buckley: Silverstone traffic jams are a joke. Lines of traffic and empty car parks to the left. Every year there's an issue.
Daniel Stafford: Definition of torture - can see the Silverstone wing and hear the cars - but caught in traffic for car park for last hour!
Jonathan Park: Big queues of traffic on way in to Silverstone. It's moving, just slowly. At least they can hear cars in distance...

Oh hello...published at 11:31 British Summer Time 3 July 2015
That rather took us all by surprise.
Nico Rosberg, having sat in the garage for most of that session, has just gone and beaten Lewis Hamilton to top spot with a time of 1:34.334, just one hundredth of a second quicker.

All that time in the pits has clearly been a setback for Rosberg, but he sets about making up for his losses with a solid first flying lap out of the pits.
He's done a 1:35.1 and is eight tenths off team-mate Hamilton.
Verstappen is still third in the Toro Rosso.

Daniel Ricciardo: "There's definitely something up with braking."
Stevens geared up for home GPpublished at 11:18 British Summer Time 3 July 2015
Andrew Benson
Chief F1 writer"'Excited' seemed to be there trendy word among drivers in the second half of the grid on Thursday. Both Force India drivers were feeling that way about their upgrade, and so was Will Stevens about Manor's.
"The back-of-the-grid team have their first upgrade of the season and Stevens hopes it will move them closer to the rest of the field. Stevens has lost the advantage he had over team-mate Roberto Merhi in the last couple of races - and he has an in-built 0.5secs advantage because of his lighter weight. But Stevens says that in Austria he was actually quicker, but that wet first qualifying disguised it. He is hoping to be ahead again at his home race this weekend, although he says he has not raced at Silverstone since his first year in Renault 3.5 in 2012."

Breaking: Refuelling will not return to F1published at 11:12 British Summer Time 3 July 2015
Formula 1 bosses have decided to abandon plans to reintroduce refuelling from 2017, writes Andrew Benson.
The idea was proposed in May but investigations revealed it would lead to a drop in on-track overtaking and too little variation in strategies.
It was dropped at a meeting of the strategy group of leading teams and officials on Wednesday.
Meanwhile, F1 boss Bernie Ecclestone is pushing to impose an engine freeze in a bid to make racing more competitive.

Then give them a rest by reading the latest Lewis Hamilton column.
The world champion could not be accused of waffling as he gave his responses to questions posed by BBC Sport readers.
Maybe he read this week that Kimi Raikkonen was voted the most popular F1 driver in a fans' survey and thought he'd take a leaf out of the Finn's monosyllabic book?
