Having a windscreen around the halo could prove to be problematic in a few cases, like the case of grosjean.
It could obstruct escaping possibilities. I believe, but can be mistaken, that you can't exit the halo sideways with a helmet on. so perhaps there is a need for more space there, who knows.
one thing is certain, having a windscreen around would definately make it impossible to escape sideways.
even if we'd limit escaping only by the top opening, then having a windscreen around in normal circumstances wouldn't hamper too much, but it's the freak accidents we would need to worry about. For example: is it possible, that in grosjean's case, the windscreen's material could have been damaged in such fashion that it could actually enter the cockpit, and not only potentially cut/hurt the driver, but also prevent the driver from escaping?
after all, the material should become strong enough to withstand debris (like the visor does), and thus, one needs to wonder: if it FOLDS into the cockpit in an accident, could the rigidity of the material prevent the driver from moving it aside to escape?
right now, we don't need to worry about these things. perhaps a solution could be a fifth height of a windscreen. like having a little 'screen' that simply deflects material from the visor area of the driver.
the simplest solution would be: leave it as it is.
as for Hulk: yes, the car needed to be flipped so he could escape. PERHAPS if the halo was higher at the front/side area, so that the driver could escape sideways an not through the top (if the driver would be bendy enough that is) this could be looked upon, but then the issue remains: if he was physically injured in such way to prevent him escaping on his own merit, then it would make little difference anyway.
fire indeed is a wholly different story.
apart from that: it's proven to work, why change this clearly successfull design?
i'm also pretty confident that the fire incident is going to get investigated.
here's a question, as i'm not sure on the matter.
Is DIESEL able to burn without being under pressure? i know about fumes being risky, but if diesel needs pressure to be able to be ignited/burn,
then wouldn't a simple solution be using DIESEL as fuel?
since F1 is intending to develop stepping over to fully sythetic fuels in the future, is it possible to make a synthetic (diesel?) fuel, which cannot burn as a fire
the way gasoline does?
