In an extraordinary situation like that, and yes even in Florida such a massive evacuation is extraordinary, some of the responsibility has to fall on individuals. The only fuel storage most people have is their vehicles, yet running out and gassing up ahead of the storm has been condemned, I’ve seen it even on FR, called hoarding. No, obviously it’s not hoarding in light of what happened in the lead up and aftermath of Irma. So, the governor’s actions were prudent, responsible and yet still not enough.
The very concept of massive evacuation needs to be revisited, with evac limited to those in the most immediate danger first, phase it by zones. It’s also responsible to have means of transport available that do not depend upon gasoline. That could be diesel, that could be natural gas, that could be electric. Electric vehicles have long been condemned on FR by some because they’re suspected of being a government-subsidized boondoggle and perhaps in many instance they are. They also famously have rather limited range. But, limited range is far superior to no range at all if your car is on empty and you can’t find any gas.
As long as electric vehicles aren’t subsidized or given tax breaks (and the GOP tax plan gets rid of at least some of that), people can drive them to their hearts’ content.
