Red Bull have indicated that they will vote against the introduction of the Halo cockpit protection for 2017.
That is despite the fact that, at the Silverstone test on Tuesday, Red Bull youngster Pierre Gasly tested the innovation for the energy drink team.
"It was strange to see something in front of me but I was surprised that it didn't change [the visibility] much," said the young Frenchman.
GP2 driver Gasly admitted, however, that he would prefer if F1 keeps its open cockpit format.
"Of course it is more risky without Halo, but everyone who drives these cars knows the risks and accepts them," he said.
Team boss Christian Horner said that he thinks 2017 is too soon for Halo to be introduced.
"I'd prefer there to be more research time taken to do the job properly, rather than rushing something through that may have other consequences," The Express quotes him as saying.
"I certainly wouldn't vote in favour at the moment."
Red Bull actually pioneered the Halo alternative, Aeroscreen, which has been put on the back burner by the team because the FIA is asking for further developments.
