Maybe, emphasizing public transportation more wouold help. We are going to have to come up with good evacuation plans for major cities.
Women and children first?
I think you just turn the highways one way.... and ask people to be nice about it. And ask them not to wait until the last minute.
I think, the plans are all there, and this satifies the requirement...but I don't think, anyone believes that we really can evacuate our big cities, when needed.
