This is not entirely dissimilar to the research that the FIA carried out into a canopy system that could be implemented - and much like then, I am still concerned that whilst a solution like this may reduce the risk of cranial injuries for the driver, it potentially increased the risk considerably for anybody in the surrounding area. Remember that when the FIA tested a canopy system under similar circumstances, the wheel itself came to rest several hundred metres away?
You end up in a situation where the risk may now be transferred from the driver to marshals or even spectators around the circuit - either that, or you might end up having to increase the height and extent of the debris fencing around the circuit. Added to that, as others have pointed out, putting a metal frame somewhere in front of the driver might potentially impede his vision - at least a canopy system, for example, could be made from transparent materials.
All in all, whilst the FIA do have noble intentions - improved driver safety - I am not entirely sure that this is the best way of going about it, given that there are a number of potential downsides as well.
The video seems to make it patently obvious how much it limits the drivers' vision. And it's already restricted enough by the cockpit surround and inadequate rear-view mirrors. It's a good idea in theory but there is no way of adequately implementing this without impeding vision and making accidents more likely. On Autosport.
And shouldn't this be in the Paul Stoddart forum?
For the moment, I think that this forum would suffice - the research in question may not just be applied to Formula 1 cars, but potentially to other open wheeled series as well. Additionally, I'd associate the PS forum with current developments in F1, whereas there is no guarantee when, or even if, this research would be applied to future F1 cars.
