Im not sure it would be needed if the government, highways agency, councils, etc, every paid any real attention to the recommendations of coroners courts, courts who themselves usually have the benefit of evidence from trained CI's.
They ain't making use of the systems thst already exist, so I i don't see that yet another separate bureaucracy will be any more successful. It'll simply be another department to ignore or make excuses for not implementing their recommendations because its not politically or financially expedient to do so.
Thats my two penneth.
