One minor comment, but if the electric grid is down, then it's likely you won't be able to pump gas either. At least, most gas stations have not planned to be functional without electricity.
Also hurricane evacuation with mass electric adoption is going to be an interesting situation to observe. It may be better than with an ICE. We’ll see.
I've never spent enough time in Texas to experience an outage, maybe Texas gas stations are far different than the rest of the US?
A lot of folks keep a 5 gallon for their lawn mower… although gas powered mowers are going the way of the dinosaur too
But yes, I tend to keep 2-4 5 gallon containers of 4 stroke gas. I’m almost certainly an outlier, but in more rural areas where you have to be self sufficient it’s not rare.
Heck, a lot of pickup trucks have diesel tanks with 12v pumps built into the bed.
Although maybe it costs more than I think? This "industry lobbyist"[1] claims $40k PER PUMP which seems much more expensive than the ~$2000/station I was estimating.
It looks like Florida started to require installation of transfer switches on stations on evacuation routes, after hurricanes in the early 2000s:

However they do not require generators on site, and only require companies with a 10 or more stations in a county to have generators available, but then only within 24 hours.
This is more regulation than I had expected!
There was great article on HN years ago about a Canadian (New Brunswick, maybe?) gas station run by a former software engineer, and how he had planned for an outage by getting a generator for his station. But when the power outage happened, he was too far away to get back to his station, and couldn't find a place to fill up to get back. Wish I could find it again...
