“Whereas a large segment of New Orleans residents with cars stayed put with the approach of a major hurricane, when that is a common occurrence there.”
Yet again you fabricate complete and utter nonsense.
Hardly.

In New Orleans, about 91% of the population has access to a car to get out of the city (American Highway Users Alliance, 2006).
Hmm ... 80 percent of the city evacuated. 91 percent had access to a car to evacuate. That meant that rougly half of those who stayed had access to a car but did not leave. Last I checked, half is a large segment.
