Maybe the real problem in New Orleans was that everyone in a position to plan for emergencies simply assumed that everyone has a car.
Think about it: if an announcement came that you had to leave your home right now because of an impending disaster, how would you get away? And if you have a car yourself, how many of your neighbours don’t? Would you remember them? How would we ensure that nobody got left behind?
I live on a small, narrow Island. My house is 3 blocks from the ocean. I have no idea what, if any, plans are in place to get me, my family, and my neighbours to safety is Katrina-style weather was on its way.
