I think it is a neat idea...BUT...as someone who spent several years with an accident investigation/safety engineering firm, the narrow edge of that plate that faces the occupants of the vehicle would be like a knife in an accident.
Perhaps one could weld a vertical piece of flat stock around/under the edge so any impact force would be attenuated over a larger area...so maybe it would still break you but wouldn't cut you as badly.
(Don't want to be a downer, but the autopsy photographs were memorable.)
