Membership of GPDA is not compulsory. For example, during the 2013 Formula One season, only 19 out of 22 active drivers were members. Joining the GPDA costs £2,000. It was announced on 13 December 2017 that all the drivers had signed up. GPDA members elect their representatives. Currently, there are three directors—Sebastian Vettel, Romain Grosjean and Alex Wurz, who also serves as chairman.
During the 2005 season the GPDA became increasingly involved in the politics of Formula One. Following the, the GPDA issued a statement supporting the case of the Michelin teams in the FIA World Motor Sport Council. Significantly, though the majority of drivers signed the statement, Michael Schumacher did not. He claimed that he was not asked to and would not have done so, in any event. The statement claimed that the FIA's proposed solutions to the problems experienced by the Michelin teams were unworkable. Schumacher claimed the problems at Indianapolis were technical rather than a safety issue. A meeting between the GPDA and FIA presidentMax Mosley, scheduled for the, was cancelled by Mosley because of statements made by David Coulthard. Mosley claimed Coulthard's statements to the media were a "distortion" of the purpose of the meeting and accused him of stirring up dissent. In retaliation the GPDA released a letter that had been sent to Mosley accusing him of jeopardising the GPDA's drive for improved safety: In 2010, upon his return to the sport as a competitor, Michael Schumacher announced that he did not intend to join the GPDA. He subsequently became a "silent member" following discussions with GPDA directors.
Notable activities
Thanks to the activism of the GPDA, the Circuit de Spa-Francorchamps was boycotted in 1969 and the Nürburgring in 1970 and after 1976, over safety concerns. In 2013, following a series of tyre blowouts at the British Grand Prix, tyre safety became a major issue, with the GPDA announcing through a statement that its member drivers would withdraw from the subsequent German Grand Prix unless remedial action was taken. In May 2015, the GPDA and Motorsport.com joined forces to allow followers of the FIA Formula 1 World Championship to voice and share their opinions about the sport through an extensive worldwide survey for fans. More than 200,000 respondents participated in the survey. In July 2015, following the death of Jules Bianchi, the GPDA announced that it felt a responsibility "to never relent in improving safety". In March 2016, following changes to the qualifying system, the GPDA released an open letter written by Jenson Button, Sebastian Vettel and Alex Wurz on behalf of all drivers saying that the sport's leadership was broken, calling the decision making within Formula One 'obsolete' and 'Ill-structured'. The GPDA believes that the decision making could 'jeopardise F1's future success'.
