Kevin Magnussen doubts the Halo will be introduced in F1, saying a new concept is likely to be developed by 2018.
With the FIA keen to introduce increased cockpit protection next season, the Halo was eventually postponed until 2018 as the teams wanted more on-track testing of the device. With a number of drivers testing the Halo at the last two races - including Jenson Button, Max Verstappen and Sergio Perez at Monza - Magnussen was asked if it was discussed in the driver briefing but believes the concept will never be introduced.
"I think it's the plan for most teams to run it at some point, isn't it?" Magnussen said. "If I could choose I'm not going to run it.
"I don't think it will come in. I don't think so. I think now they've delayed it they will come up with something better.
"They need to come up with something better. The Halo isn't going to go on. If it was then it would come on next year. They've obviously seen that they can come up with something better and they need more time to do it."
Asked if any other concept should be developed in private after mixed feedback to the Halo, Magnussen replied: "I don't know if it's better to have outside the public eye. It would probably be a quicker process to have it running all the time but you can't really have that in a season. We'll see how they get on.
"The FIA should have a car in a way, testing it, but that would be very expensive. Pirelli should have a car testing tyres and that would be very expensive as well..."
