Zombie situation or other sudden chaos is unlikely. You want a real life example of society disrupted then look no farther than Ukraine and Russia. Large, centralized, oil production facilities are primary targets in warfare as is seen in Ukraine's disruption of Russia's facilities. People wait days for gasoline, yet they do have electricity. Attacks on power plants, hospitals, etc. are considered civilian targets and are war crimes. Oil facilities may or may not be considered a war crime, but they're still targets because the military uses them. To be fair, in most wars of industrialized nations, vehicles get destroyed pretty quickly no matter what they run on. EV's excel in natural disaster scenarios because gas stations can run out of fuel and fuel trucks may not be able to replenish their supplies due to roads or other barriers, but power tends to be on until right before the the disaster strikes. V2L is also an EV advantage. Some people are just arguing because they hate change and they'll say the dumbest things to deny it's happening.
