    Then there is the question of whether the screen can sustain the weight of the car if it were upside down. Then there is the question of how it disintegrates
    upon hard impact with amco barriers. If it shatters into elongated pieces, they could transform from a protector into a harmful projectile during high impact accidents.
    WEC have windscreens on the LMP1 cars and they have dirt/oil remains as well on the windscreen which they have solved it by simplywiping the windscreen every time the car
    is making a pit stop. Not really a big problem. Rain might be an issue since the windscreens are quite small/round which might be tricky for windscreen wipers but I am sure
    that the engineers will be able to solve that. I do think there is some kind of lubricant/spray that you can apply to the windscreen which prevents waterdrops from "sticking"
    to the windscreen. I do not know if it would work in racing though,

    Durability of he glass is not different to WEC, modern acrylic glass is incredibly strong and is not really a concern.
    If it is strong enough for WEC (which also have bigger windscreens then F1) then it should be strong enough for F1 as well.
    ...Funny how ev'rything was roses when we held on to the guns...

    I'm not sure why it was scrapped Andy.

    Here's a closed cockpit car that ran in the 1919 Indianapolis 500 driven by Roscoe Sarles. The car won 20 races in its career. It was mostly driven by racing legend Barney Oldfield.

    This is my opinion and to the best of my knowledge, that is, if I'm not joking

    Here's Junior Johnson's enclosed cockpit car for the 1963 Indianapolis 500. He practiced in the Kurtis Offenhauser but did not qualify.

    Do we want closed cockpits?

    According to the Wikipedia article on the BT19, Brabham's designer Ron Tauranac had been doing wind tunnel research since 1963. I guess that cockpit was fruit of that research.
    It seems he had a record of rejecting aerodynamic improvements that weren't effective enough to justify their weight or complexity, so maybe that was the fate of the Brabham closed cockpit.

    I think closed cockpit is a good idea. It believe it adds down force and possibly more protection.
