Formula One veteran Jenson Button has revealed that he has changed his mind over the debate surrounding Formula One adopting closed cockpits. After somewhat of a recent spike in head injury-induced fatalities in motorsports including the more publicised deaths of former Marussia driver Jules Bianchi and Indy Car driver Justin Wilson, the FIA are now under serious pressure from the Grand Prix Drivers Association (GPDA) to make substantial progress towards implementing closed-cockpits for Formula One as soon as possible. Speaking to reporters ahead of this weekends Italian Grand Prix, Button said, "This shouldn’t happen now in motor sport. It’s not the ‘70s, we should know better. I was one of many who said we should keep open cockpit racing but we’ve had enough now, it’s time to do something serious about it, not just change things like the headrests." The current cockpits have had a vast amount of research and experimentation put into them in terms of driver safety with raised head rests and such, but obviously there are still safety deficiencies that have been exposed over the years. However there are several complexities to designing a canopy or cockpit protection system, for example, a jet fighter-styled canopy would prove to be the most aerodynamically effective method, and would probably look the most aesthetically pleasing, but it could cause problems with cockpit temperatures as it will essentially act like a greenhouse, and will compromise the ability of the driver to exit the vehicle quickly in case of a fire or if another hazard presents itself. More recently, the Mercedes F1 team released a mock-up design of a potential solution with a halo-like structure that could help protect the driver from flying debris, or more significant obstacles like removal vehicles. However issues of driver visibility do come into question when the attachment point is directly obstructing the drivers' line of sight along the sagittal plane. There's also the issue of teams using this device for aerodynamic purposes and potentially compromising the effectiveness its' safety properties. The open cockpit philosophy is something that is synonymous with Formula One, and given the incredible forces involved in the accident that Jules Bianchi tragically suffered, it is questionable as to whether or not a closed cockpit would have saved him. However driver safety is paramount, and if closed cockpits are something that could have prevented the deaths of Bianchi and Wilson, then it's unquestionably something worth doing, however it needs to be done the right way. Do you think Formula One should invest in closed cockpits?
