> You can't convert electric to biodiesel like you can gas engines No need. Get yourself a couple solar panels and fuel up directly. If there's no sun, use your biodiesel to run a generator. > Electric cars carry around a giant explosive that isn't easily armored, if you become a nuisance they can roast you with the battery, or even perhaps destroy the battery remotely via the car's software Gasoline is more explosive than lithium batteries. It has a higher energy density. That's why you can drive further on a tank of gas than you can on a "tank" of electricity. > Range Gas is easier to control because almost nobody can make gas out of nothing. The same is not true of electricity. You can solar, hydro, wind, or just plain use a gas generator. There are more options SHTF with electricity than with gas. Also, gas engines are far more complex. That means more potential failure points. In a SHTF scenario you want to maximize options and minimize potential points of failure. Gas loses on all accounts. It *seems* easier because it's more familiar to people. It's inherent limitations and tradeoffs are taken for granted because we're so used to them. > Limited ability to be armored (I doubt Teslas have the requisite torque necessary to haul armor along with their heavy batteries) Electric motors have more torque than gasoline/Diesel motors. That's the reason Diesel train locomotives use electric motors to move the train. The Diesel part just generates the power for the electric motors. https://science.howstuffworks.com/transport/engines-equipment/diesel-locomotive.htm
