Jenson Button feels the FIA has been "more open" to driver opinions since they wrote an open letter questioning the state of Formula One earlier this season.

In March the Grand Prix Drivers' Association (GPDA), of which Button is a director, called for an overhaul of F1's "obsolete and ill-structured" decision-making process. It followed the controversy over elimination qualifying, which could not be scrapped in time for the Bahrain Grand Prix despite a farcical debut in Australia.

F1's drivers have no official voting power on new regulations, which are devised by F1's Strategy Group, voted on by the F1 Commission and rubber-stamped by the FIA's World Motor Sport Council. The letter called on F1 to devise a "master plan" to restructure this format to prevent similar "gridlock" in future.

Though there has been no change to the structure Button thinks the FIA has been more willing to listen to what drivers have to say since the GPDA went public.

"We feel that we do have a say anyway and since our comments earlier in the year, the FIA have been more open to our opinions, but they would prefer it is behind closed doors rather than in the press," Button said. "I think that we have a reasonable say but you always want more because you always think we have more to give, rather than take, and that's definitely what we're here to do -- make the sport a better place."

Bernie Ecclestone memorably replied to the open letter by calling the drivers "windbags", saying they should keep opinions to themselves. Button thinks the letter proved drivers care about improving the sport as much as possible.

"I think it showed to the world that there are issues in F1 and the drivers know they are issues and are willing to help. Of course we got replies from certain individuals and I think our comments were valid and I think they understand that.

"The important thing is that we're all willing to what we can to improve the sport, because the sport's not in a bad place but it's not as good as it should be and not as good as it will be. Things like this, little regulations with yellow flags, the radio, that we need to come up with a solution that works for us all."
