Button getting used to winning

The Briton has enjoyed a dream start to the season, winning the first two races in Australia and Malaysia as his Brawn GP team looks like the squad to beat at the moment.

Button has moved to the top of the standings following two dismal seasons with the Honda Racing team.

He has already scored more points in the first two races of 2009 than in 2007 and 2008 combined.

Although cautious about the competition, the Briton admits he is already getting used to being on the top step of the podium.

"It's quite weird how quickly you can get used to being at the front after two pretty poor seasons," Button told reporters in China. "When you get on the podium it's not like, 'Oh my god this is the most amazing experience ever'. It's more a case of, 'OK, we've done that one. Let's move on to the next race'.

"In a way that's good, I suppose. If I don't win this weekend it will be a slight disappointment, but you have to remember it's a 17-race championship.

"If you go out to win every race and you end up being disappointed to finish second, third or a little bit worse, I don't think you have the right mentality.

"It's not a one- or two-race season - it's a big event that goes on for a long time and I think you have to be a little bit clever in the way you work, grabbing points when you can. Scoring in every race is the key in F1 and always has been."

Button says his rivals are likely to catch up quickly, although he admits the in-season testing ban is an advantage for his own team.

"Well, I've got a very competitive team-mate who will make life difficult for me and the Toyota looks very competitive, but it's not just Toyota and Williams that have been quick," he added.

"Red Bull has, too, and I'm sure people will get their acts together very quickly. We've got a head start having done a very good job over the winter, we've obviously done a good job in many areas with our car - not just the diffuser - and I think it's going to take people a little bit of time to catch up.

"They know where they need to improve, though, so they will catch us up, or try to, and it won't be long, for sure.

"The lack of testing is a good thing for us because we have an advantage and teams can no longer just throw stuff on the car, even if it doesn't look good in the wind tunnel, to see how it performs on the track.

"Even so, I think people's wind tunnels are very good and I think we'll see a few teams getting close to us and becoming more competitive."

The Brawn GP driver said he was happy that the controversy over the design of the diffusers was now behind, following the FIA's decision to rule it legal.

"Not really," he said when asked if the court result was another victory. "It was just a nice feeling to put it behind us and now we can concentrate on doing our proper job. In a way it was expected. You're obviously a bit worried, because you never know what might happen, but it wasn't like a shock when I found out."
