Toto Wolff has labelled the Halo cockpit protection device as a "dreadful" addition to an F1 car as his Mercedes team works on the best way to incorporate it into its 2018 design.
Following more than eight years of dedicated research into cockpit protection in single seaters, the FIA will make Halo mandatory on Formula One cars next year. The device is designed to deflect flying objects away from the driver's head and is formed by a titanium structure wrapped in carbon fibre above the cockpit .
In 17 case studies of serious accidents carried out by the FIA, Halo would have had a beneficial outcome in 15 while the other two would have proved neutral.
