Formula 1 drivers are pushing for increased cockpit head protection and higher-performance tyres from 2017.
Grand Prix Drivers’ Association chairman Alexander Wurz said drivers unanimously agreed on the “swift implementation” of head protection.
The Austrian, 41, added the drivers also concurred on wanting to “help and support Pirelli to construct a tyre fit for maximum-attack racing”.
Drivers dislike the existing tyres as they can rarely push flat out on them.
However, they rarely speak out publicly after being warned to keep their thoughts private.
Governing body the FIA has been pursuing ways of protecting drivers’ heads in open cockpits from frontal impacts for some years, but the issue has come into sharper focus following a series of deaths across motorsport.
In July last year, former Marussia driver Jules Bianchi died as a result of severe head injuries sustained in a crash at the Japanese Grand Prix 10 months earlier. Just a month later, ex-F1 driver Justin Wilson was killed after being struck by flying debris during an IndyCar race in America.
