From next year's Australian Grand Prix the halo cockpit ring will be imposed on Formula 1 after the FIA forced through regulation changes despite allegedly nine of the 10 teams being opposed to the introduction of the device pending further trials.
Over three years in the making - and delayed by a year - the halo was developed by Mercedes in reaction to a sequence of deaths and injuries in single-seaters. So it is particularly ironic that the team's non-executive chairman, Niki Lauda - who suffered horrific injuries in an accident 41 years ago next week - is one of the halo's most vocal critics, calling the device "the wrong one" and "an overreaction".
A tacit paddock war has waged over the halo, for the anti party does not wish to appear overly macho or insensitive to the very real risks posed by motorsport, despite the non-compromise stance adopted by the governing body in this regard. Equally the pro lobby does not wish to be seen to be overly politically correct, for danger sells, as any high-wire artist can attest.
