David Coulthard concedes Sunday's British GP could be his final home race, but insists he's not ready to retire just yet.

At the age of 37 Coulthard is the oldest driver on the grid, with this season being his 14th successive year as a Formula One driver.

But despite his longevity in the sport, time is fast running out for Coulthard with many wondering if this year's Championship could prove to be his last.

And although he hopes it isn't, the Red Bull driver says should Sunday's race prove to be the last time he competes at home as a F1 driver he'd find a way to deal with it.

"In theory it should be. We're all different, and I'm quite a realist," Coulthard told Autosport.

"When something has happened, or a decision has been taken or whatever it happens to be, it's not something I dwell on, I just get on with the next thing.

"It's just one of those things. When that moment comes, it's the journey of life. You just move on to the next thing.

"I'm currently a grand prix driver, I have been for many seasons, and I'm sitting here still as a grand prix driver because I still enjoy it, and I get a buzz from it, and clearly I deliver a value enough for the team to commit to me for the last few years.

"There will be a point, naturally, where that's not going to continue and... boo hoo, you know? There are a lot of worse things that can happen to you. You just move on to the next challenge."

However, for now Coulthard is concentrating on the upcoming weekend's events and the thrill of racing on home soil.

"Driving down Hangar Straight to Stowe Corner, and seeing all of the crowd standing at the side of the track, that is particularly special at Silverstone because it's a British crowd, and you see the British flags, and the home of motorsport is in Britain. So that's a feel-good moment," he said.

"A lot of tracks you don't even bother looking out at the grandstands, but when you are on Hangar Straight you're not driving - you're just sitting on the straight waiting until you get to the braking point.

"So you soak up the atmosphere. And I've always been like that since 1994, and I will be doing exactly the same when I race there in a couple of weeks."

He added: "Pointswise it's just another race, but in terms of atmosphere, the feel-good factor, the history, all of those things are special. Monaco is special because of all of those reasons that we know.

"Magny-Cours is not particularly special - it's another grand prix, and it's a nice enough track, it's just not a great venue."
