I own multiple vehicles, every single one of them is capable of going 1000km on a single tank of gas, and seeing as I live close to border with Russia I keep at least one of them (4x4 capable one) at full tank at all times.

What EV can do at least half of that?

EDIT: To add to AM radio in said car I also have CB Radio with detachable (magnetic) antenna, just in case.

Almost nobody behaves like you do, though. At any given moment there are tons of cars in garages that have 10% of a tank.

That is true, but a gas or diesel vehicle can get refilled in 10 minutes, without consuming much power (a small generator is enough to run pumps at a gas station).

And there are 4x4 diesel trucks like Excursions and Suburbans that can carry 8 to 12 people in leather comfort for 700 miles, even over rough terrain (rough terrain shortens your range, just like anything.)

In a scenario where I need to drive many hundreds of miles to get to safety and there is no working infrastructure for charging an EV, I'd expect every gas station to run out of gas pretty darn quickly.

It’s easier to store, ration, and fill gas for gas cars than electricity for electric ones.

Maybe that won’t always be the case, but it is now.

Electric cars are a luxury atm.

Emergency services can step in and easily provide emergency fuel, charging though?

Imagine this: a giant semi-truck loads up and dumps 45,000 gallons of gasoline into invisible, underground tanks in about twenty minutes.

Now, try to imagine that could happen for electricity. (It's the same reason why datacenters always have diesel generators.)

With gas vehicles it's trivial to keep extra fuel in portable containers, if the situation warrants it. That extra range could easily be the difference between getting out of a disaster zone or not.

Heck I'm hardly a prepper or living in a risky area but I have an extra fuel container in my garage simply because I sometimes drive through remote areas and having some extra fuel in the back is a worthwhile safety measure.

Disasters are known to happen at night. Cars can drive on terrain we just usually don't because it's seen as impolite. This isn't about transportation (or the width of your tires) it's about having a layer of security, some storage for more than what you can physically carry, a place to sleep off the ground, and shelter from the weather. Plus, you know, a radio.

you just described a bikepacking bike.

Well, aside from the physical security aspect, sure. There are more than other people to be afraid of. Animals are severely annoying if you're out in the wilderness with something like food.
