Nelson Mandela is being praised around the world for his work in overcoming apartheid and promoting integration and understanding among racial groups, but he also has a legacy in traffic safety. His great -granddaughter Zenani was killed in a car crash in South Africa in 2010. Out of that tragedy came the worldwide Long Short Walk campaign for pedestrian and traffic safety, which I wrote about on this blog on May 14,2013. At the Global Youth Traffic Safety Month event in Washington DC on May 8, I had the honor of meeting Kweku Mandela, Nelson’s grandson and a cousin of Zenani. Perhaps one measure of Nelson Mandela’s worldwide influence was that he lost his granddaughter in 2010 — and within two years he and his family had founded and promoted a worldwide advocacy movement in her honor.
