You seem to forget that such a large scale power outage will also kill the pumps that pump the fuel into your vehicle. If you run out of fuel in the affected area, your car also cannot ‘get charged & going again’ until the electricity powering those fuel pumps is restored.
IF you happen to have a fuel tank at home, with a hand pump, that is a different story.
You can siphon gas in a pinch.
Some areas in Fl require a separate power system to power the gas pumps if the electricity goes down. BTW, when leaving fora hurricane, one is generally ahead of the loss of power areas. Therefore, unless they run dry, they can pump gas. How long does it take to recharge a low battery if one can find a charging station?
