On Thursday, the Strategy Group will begin voting on whether to implement the Halo cockpit protection device for 2017. To say the issue has divided F1 is an understatement -- it has led to contrasting opinions among drivers, team bosses and fans. If implemented, it would be one of the most significant changes to F1 cars in the history of the world championship.F1s decision-making process is complicated, and if the Strategy Group (made up of six teams, the FIA, and commercial rights holder Bernie Ecclestone) approves its introduction it will go to the F1 Commission and then the World Motor Sport Council for ratification. However, with the FIA pushing hard for its introduction those final two stages could be a formality if it makes it through Thursdays vote.Why now?A more focused push for cockpit protection started in 2009 when Henry Surtees, son of former world champion John, was killed by a loose wheel in a Formula 2 race. Just over a week later, Felipe Massa suffered life-threatening injuries when hit in the head by a loose spring during practice for the Hungarian Grand Prix. The issue returned to prominence again after Jules Bianchis collision with a recovery vehicle at the 2014 Japanese Grand Prix, which led to his death a year later, though a subsequent investigation found cockpit protection would have made no difference to his injuries.The death of Justin Wilson at an IndyCar race last year -- the former F1 driver was killed when struck by a piece of debris from another car -- was met with shock in the motor racing world and eventually promted the Grand Prix Drivers Association (GPDA) to call for the implementation of cockpit protection by 2017. The radical rule changes for next year made a provision for some form of cockpit protection?when agreed upon earlier this season.?The deviceHalo has gone through a steady evolution since its introduction by Ferrari during winter testing in February. The introduction of Halo 2 in Austria unveiled a lighter, stronger prototype made of titanium.One of the notable changes was to make the arc wider to eradicate the risk of a driver hitting his head on the device during an impact. Extrication tests took place in the Red Bull Ring pit lane before it was run on track at the following round in Silverstone and again by Red Bull at the in-season test.Arguments for and againstThe debate around Halo has centred around four points: aesthetics, visibility, driver extraction and, in a wider argument, about the DNA of open wheel racing itself. Lewis Hamilton memorably called the Halo device the worst looking mod in Formula One history when it was unveiled in March. However, Sebastian Vettel countered this line of argument by saying the Halo can look as ugly as possible if it achieves the goal of saving lives.As for visibility, only three drivers have actually driven a car with the Halo attached, and each at slow speeds on an installation lap. On his most recent test at Silverstone, Sebastian Vettel voiced concerns about visibility above the drivers head, while some have questioned how drivers will navigate an uphill corner like Belgiums notorious Eau Rouge with their vision impaired. It still remains to be seen how drivers fare in a car at racing speeds and with other cars in the vicinity.Driver extrication was an early criticism levelled towards cockpit protection, with critics suggesting the length of time to complete would be a safety hazard in itself. However, the FIA is happy with the extrication tests which have taken place so far, saying the benefits outweigh any negatives. After his terrifying shunt in Australia, Fernando Alonso said a Halo would have been very welcome regardless of how long it took him to get out of the car.The final point concerns the fact that the introduction of Halo would perhaps be the most significant safety measure in the history of F1 cars in terms of aesthetics. Niki Lauda recently said the introduction of Halo risked destroying the DNA of Formula One, which has featured open cockpits since the inaugural world championship in 1950. However, as others such as Vettel and Nico Rosberg have pointed out, F1s history has also involved gradual and, at times, radical changes to improve the safety of drivers.Recent developmentsThe introduction of Halo 2 at Silverstone was followed by an FIA presentation on Halo to drivers ahead of the Hungarian Grand Prix. That presentation centred on how Halo would have helped in a number of previous accidents and was enough to change Hamiltons previously staunch opposition.The FIA put forward the fact that based on previous accidents the chances of survival are 17 percent greater with Halo on their car. Hamilton has previously advocated closing the cockpit off completely, something which has featured on concept car designs released by Red Bull, McLaren and Ferrari in previous years.?AlternativesThe Halo was not the only cockpit device being considered for implementation next year. Red Bull tabled a concept of its own, the Aeroscreen, which first debuted in Russia and was generally more popular among drivers and fans alike. The concept featured two supports instead of one for the main structure and a protective windscreen in front of the cockpit.Despite the Aeroscreens popularity, Halo was closer to realisation when the FIA made a decision in May to pursue one concept rather than continue splitting its resources. However, it is important to note a canopy has not been written off for 2018 or beyond, and is seen by many as the sensible long-term solution for cockpit protection in Formula One. Therefore it is a concept that may well be revisited in 2017, regardless of whether Halo is implemented or not.

CHASKA, Minn. -- Rory McIlroy insists there will be no retaliation from home fans in 2018 when Europe attempt to regain the Ryder Cup which was lost in emphatic fashion at Hazeltine.Team USA won the biennial contest for the first time since 2008 with a 17-11 victory in front of raucous crowds in Minnesota, Davis Loves side inflicting Europes heaviest defeat for 35 years.McIlroy bore the brunt of the heckling over the first two days of competition and ultimately asked for one man who shouted vulgar abuse to be ejected, with Ryder Cup officials saying on Sunday they would adopt a zero-tolerance approach.First and foremost, we wouldnt encourage any sort of retaliation, McIlroy said of the next contest at Le Golf National in Paris. Thats just not who we are. Thats not what we do.We want to play this tournament in the manner in which it should be played. And between us, the 12 players and vice-captains and captains on this team and between the 12 players on the U.S. team, it was played in the manner in which it should have been played.We have no problems with anyone on either team, and really, its just a very small minority; 95 percent of thee people out there, the American gallery are absolutely fantastic, they really are.ddddddddddddBut this week, at times, it went a little bit too far. But you know, thats to be expected. When you are teeing off at 7:35 in the morning, youre seeing people on the first tee with a beer in their hand and matches arent finishing until 4:30, 5:00 in the afternoon, I know I would be done at that point. I dont know what I would be saying!So it has to be expected. A couple of people out there crossed the line, but well take it on the chin. Well move on and well definitely not encourage anything like that to happen in France next time around.Captain Darren Clarke and Lee Westwood were keen to emphasise that American players and vice-captains tried to maintain order during the matches.Westwood said: Fair play to Bubba Watson and the two lads that myself and Danny [Willett] were playing yesterday afternoon [J.B. Holmes and Ryan Moore].They were trying to cut all that off and they were doing their bit to stop that as well.
