Read the link. Hint: no, they aren't. The main absorbtion of energy is all in the styrofoam. If the shell shattered but the styrofoam didn't compress then no significant force dissipation happened. Some did, yes, but not enough to have prevented anything more than cuts & scrapes.

They did, actually. That was in the article.
