I think the challenge of closed cockpits is that it brings on new problems.
I has to be easily opened for whatever reason. Potentially in life threatening situations.
It must be able to open from the outside as well as from inside.
It must not obstruct vision (already limited in current F1 cockpits)
Higher heat build up? Needing additional cooling solutions
How strong is strong? Only resist impacts from flying debris up to what point of energy? Does that mean the structure of the survival cell can change? Can it help to make the monocoque stronger? How heavier is that? Will the driver require mechanical assistance for open the cockpit?
It's an interesting engineering challenge. Not impossible, but I can see that implementation will be a tough one.
Opening: Driver has standard releases at aft, exterior has T handle pins in 3 locations for responders, rear and aft. All current boat capsules have these.
Obstructed vision. Mirrors can be integrated into the canopy rather easily and may even be more stable.
Heat buildup: Cool suits are available in NASCAR now, weight penalty, for sure, as well as fire suppression and breathing apparatus if deemed necessary.
Strength: These canopies at the speeds F1 run are virtually impenetrable. See above shot,all fighter jets have bird strike ratings that are very high.
Structurally the cell may change a bit for mounting, but also have some parts of the cell able to be integrated, such as the current 'horse collar' snap ins.
One thing for sure that will be hard to cope with is the additional weight and it's high COG placement.
I am fully confident that the best of the best in engineering, which F1 claims to be, could pull off some really clever things with this safety feature, especially in it's aero effects.
