General Motors CEO Mary Barra, left, is conferred an honorary Doctor of Engineering degree by Michigan President Mary Sue Coleman, before addressing the University of Michigan graduates at a commencement ceremony Saturday, May 3, 2014 in Ann Arbor, Mich. Barra, the first woman to lead a major automaker, took the top spot at GM in January, just as a deadly ignition switch problem was starting to surface. Barra urged the students to be honest in every aspect of their lives, and to use their optimism and propensity for inclusion to rethink outdated assumptions and expose and correct injustice.
