@ricci As a former grad student under end of career tenured professors phoning it in, I do not disagree with your thesis statement, but I do disagree with your justification. The one guy had been so apathetic for so long, his transportation policy class didn't mention the last two FIVE-YEAR transportation acts. Any interaction with him was the same speech trying to put me off doing a PhD, probably because he didn't want to supervise it.
