Only if your power grid is functioning, which I wouldn't expect to be the case in most major disaster situations. Otherwise you'll be stuck burning fuel in a generator to charge your car.
EDIT: the other great thing about liquid fuel is it doesn't weigh very much. Diesel is 7.1lb/gal so if your diesel car gets 32mpg (like mine does) you get 4.5mi/lb. With 1500lb on a trailer--let's say it only gets 20mpg or 2.8mi/lb towing--that's an extra 4200mi of range. That's enough to go from Boston to Anchorage without refueling. It's also a much more easily transferable energy source than electrons--all you need to do is pour liquid from one container into another. You don't need some fancy battery charger that needs stable power at such and such Volts, Watts, and Hz.. So, no, in a disaster or war situation I doubt the EVs will work at all.
Another problem with going to the gas station is payment. No internet means no credit cards or whiz-bang apple wallet stuff.
> it's a fungible asset
Cool, let me put that in my gas-powered ICE car. Its so fungible.
And I mean practically every household has a 200gal tank of diesel in their apartment and suburban household. Only the oddballs wouldn't have it.

Hmm, makes me think maybe most households aren't in the same situation here. Most households are going to be in the same situation if their car is an ICE versus an EV. Maybe ever so slightly better in the EV, because at least they're likely to already be charged to like 90% every night versus somewhere between nearly empty to full. In the end, if the grid stops working chances are they're going to have a hard time getting more gas until they get someplace where the grid is functioning.
That's a choice, definitely the more common one in the US, but not the only one. I've been driving diesel cars for my entire adult life--better part of a quarter century now.
Gasoline is by far the worst of the common fuels--diesel, gasoline, and propane. They make propane dinghy outboards for exactly this reason--carrying gasoline just for the dinghy really inconveniences a boat whereas they already have propane and diesel onboard for the engine and galley. Diesel and propane both have ~infinite shelf life.
> Hmm, makes me think maybe most households aren't in the same situation here.
Yes, I've prioritized access to nature and quiet over pretty much everything else. That's not normally what people who do computers for job do.

Its definitely much shorter than a decade, but if stored really well more than a year is pretty doable. 2+ years can be a gamble though. And if it causes problems, it might cause some serious problems. Want to gamble on your generator during an emergency?
I've definitely had some gas sitting in a tank with stabilizer last a couple of years. I've definitely had gas sitting in a tank go bad in under a year.
1. Air leaks in the fuel system. If any of the negative pressure components have an air leak you'll be sucking air. This means less fuel, but more crucially less lubrication. High pressure injection pumps are meant to be lubricated by fuel.
2. Algae. Sometimes a fuel system can be contaminated by extremophiles that grow in untreated fuel. This will merely clog filters, and in the absence of water or air leaks will cause only fuel starvation and no engine damage.
3. Water. Water will turn into a steam bubble in the vacuum of the suction stroke of the injector pump, and then on the subsequent compression stroke the bubble will cavitate--turn inside out--and blast the wall of the injection pump cylinder with an extremely concentrated high temperature jet. Doing this hundreds of times per second wreaks havoc on the poor engine.
So if your fuel is dry and clean you're good.
For the pollution question, my retort is "which kind?" I claim diesels create more NOx and soot for less CO2. So, which is your priority?

They are talking about diesel fuel, which definitely has a shelf life without additives to keep it from turning to mush.
I'd say "it depends". In a dense city I see NOx and soot as being a higher priority. If you're out in the sticks, probably your contribution to global warming (CO2 et al) should be weighted more heavily.
Or in a generator, for use in your EV :-) Whereas it will be hard to run your diesel car or tractor on solar power.
Not defending EV in particular but you can't expect everyone to have that.
If the apocalypse comes, EVs will be running for a lot longer than ICEs.
An AM capable emergency radio is a few bucks on Amazon, and they have a hand spin generator next to batteries and a 12V or other wide-range DC input to attach a regular wall wart or a tiny solar panel.
A hybrid will be very competitive and likely do better if it's cold (maybe a jam because of a blizzard)
