What are you afraid of happening?

This is such a perverse and anxious fear imo

A reasonable scenario might be a cyberattack taking down large portions of the grid for a prolonged time. It's not impossible to achieve something like that, Stuxnet proved the concept of corrupting PLCs driving powerplants ages ago.

Alternatively, even outside a cyberwar scenario, bad weather has been shown to take down power grids for entire regions for days, sometimes weeks.

Where I live, we have typhoons which depending on the direction they arrive in can result in all the gas stations being out of gas for 2+ days. Meanwhile the grid keeps on ticking.

If they've taken down large portions of the grid for a prolonged period of time you're also not going to have much gasoline left.

Once again, as someone who actually lived through those scenarios multiple times, when the gas pumps go down you're usually shit outta luck on getting gas.

When the grid goes down for days, the gas you have in your gas car + any random fuel tanks you have in your garage is what you have. Don't expect anything else unless you plan to take it at gunpoint.
