Free transportation was available I believe.

You weren't aware of this fact when you made the post condemning those who stayed. My response merely pointed out a shortcoming in your reasoning process, cautioning you not to jump to conclusions before you have the facts.

More people are killed in the aftermath of the storm, especially during cleanup.

Five people are dead and 115 have been evacuated to a local hospital from a nursing home that had no air conditioning following Hurricane Irma, the police said Wednesday. Two employees of the nursing home, the Rehabilitation Center at Hollywood Hills, said that it had power but that at some point the air conditioning stopped working. Three died at the facility and two more during the evacuation to a nearby hospital, city officials said.

Roughly 160 nursing homes in Florida remained without commercial power on Wednesday morning, according to the state’s tracking system. Most of those nursing homes lacked a generator that could run air conditioning. High temperatures were becoming a major concern.

The rehabilitation center is located across the street from Memorial Regional Hospital, the flagship facility of the Memorial Healthcare System and one of the largest hospitals in the state. An official from Memorial said that the healthcare network was helping with evacuating people from the rehabilitation center, which is not part of the Memorial system, and will take some to their other hospitals in the region.
The facility’s administrator did not return messages left by The Washington Post.
At a news conference, Florida Power and Light said it serviced portions of the facility. Robert Gould, the utility’s chief communications officer, said he understood that certain parts of the facility had power. He said Broward County did not list the facility as critical infrastructure — the places where restoring power is a top priority after a storm — in a hurricane planning meeting earlier this year.
“This facility was not listed as a top critical” by Broward County, Gould said.
“What we’ve seen is something extremely tragic that points to the need to having plans in advance when it comes to emergency preparation. I would be remiss if i didn’t say our deepest sympathies goes out to the families of those lost their lives,” Gould said.

Here are questions to ponder at some time when the definitive data are available:

What was the fatality/injury rate among those who elected to stay on the keys during Irma? How does that compare with those who evacuated?

So far, I have not seen anything about large numbers of fatalities among those who remained, nor, for that matter, anything about incidents among the evacuees. Indeed, the number of fatalities (somewhere in the mid-50s) seems quite low considering the population at risk in this storm.

Presumably one would leave because remaining would expose one to a significant chance of dying. If that is not the case, there is a significant advantage to sheltering in place - nothing works like home field advantage...

Which kind of indicates that it takes out people earlier, but those people where likely to have died soon anyways.
