Free transport does not mean you can get out. The problem are not the healthy and mobile people, they generally survive, unless they do something stupid or have bad luck.

The problem are the less mobile and poor people. The ones that are disabled, but not in care facilities. So depending on them self, but with an emergency, they just are not mobile enough to do something about it and too poor to hire somebody. If you lack somebody to take care of you then than they have a big problem.

These are generally represented in the 65+ category. In Katherina, the majority of deaths are in that poorer 65+ category.
