Good point. Further, "risk" is not on the list of GM words. But, depending on the motivation for the list, which if car marketing is similar to what it has ever been is to suggest that "new car" = "it's a wonderful life", it might well get on it quickly if everyone started talking about "risk" and "residual risk" as the standards require.
