"Autostrade, which handles media queries on behalf of the subcontractor, Spea Engineering, declined to comment."
I guess that's what bothers me a bit - is that there is a somewhat in depth investigation regarding the technical explanation, but a big shrug at hitting the wall on explanation of management failures, which IMHO should go all the way up thru the ownership conglomerate.
