I'm not unsympathetic to him at all but, as the Volkswagen emissions-test rigging scandal continued to erupt this week, after the EPA's shock Friday night recall order announcement a week ago, Volkswagen's CEO Martin Winterkorn took the honourable and brave course, obviously after considerable discussion and thought, and, finally, offered the supervisory board his head on a plate - and his resignation was accepted. It was a sad and ignomonious end to a long and successful career.
