Millions tried evacuating Houston before Rita hit shortly after Katrina.
That was a disaster in itself.

People that haven’t been in something like that have no idea of the problems.
Housing becomes a major problem for hundreds of miles in order to place that
many people.
Yep, you can’t evacuate millions of people unless you have a place to put them. I didn’t evacuate and am dry (so far). I’m sure a lot of people that live in low lying areas did evacuate (I know a few who did). They are now issuing mandatory evacuations for areas south of me due to Brazos River cresting.
