If you try to escape a wide-area emergency or disaster in an electric vehicle you will travel 300 miles, then die. Gas stations can refuel vehicles in 5 minutes or less, with stations having up to 20 ports. Extra capacity can be added by trucking in more fuel. Fuel stations can be improvised by fueling directly from tankers. Fuel stations can operate independently of grid power by burning their own product in generators. Every gas station acts as a small reservoir of energy, conveniently placed along every evacuation route. Charging stations can process vehicles in 2 hours, with a max of 8 to 10 ports, capacity cannot be rapidly added nor improvised. If the grid goes down, so does the station. So what happens when 200,000 people flee a metropolitan area in electric vehicles? They bottleneck at stations 300 miles from the epicenter. Then they riot and die.
