As someone who has actually lived through multiple major catastrophes where fuel couldn't get delivered for days and electricity was out for days, when the pumps stop working there is no gas. Don't assume the gasoline the police and fire department have will be there for you. It's there for the first responders. They don't have infinite supply. Their supply is extra expensive to handle compared to when things were working. You've now got many thousands of families all trying to get to the two or three operating fuel stations...trust me they're not open to the public! When you're out of gas, you're out of gas.

Meanwhile, those with solar panels not reliant on grid-tie, they can continue to charge their vehicles.
