    No, there are no false assumptions, the rough 25% degrade in efficiency is based on articles that cover this sort of thing for people trying to make their houses go solar that have done all the math on this.

    Sure, depending on your /exact/ set up, certain parts of this will vary slightly, but you still end up in the ballpark of needing a roughly suburban front yard sized solar array and battery/inverter set up to charge a CyberTruck off of one day’s electricity.

    Now, having a much smaller solar array to charge maybe an E-Bike?

    Thats a faaaaar more apocalypse friendly concept.

    It doesnt matter if certain other electric vehicles are slightly more efficient in terms of range per kWh: you are still gonna end up needing a fairly large solar array.

    An EV for an apocalypse scenario is ludicrous.

    You wont have a home charger or network of chargers if the grid goes down, and if it takes a stupendous amount of effort and time to set up a solar array giving you the ability to basically light local foraging in an EV…

    A simple bicycle is faaar more practical, and an E-Bike gives you an enhanced ability to do that for faaar less investment.

    Or you could have a gas powered vehicle with fuel stabilizer added to the gasoline. Thats pretty cheap and easy to stock pile, and you could put said fuel cans in your car for actual extended range.

    Sorry, theres no societal collapse scenario where EVs make any sense.

    They simply require /infrastructure/, and the hallmark of an apocalypse scenario is /infrastructure is broken/.

      See that’s where your argument for gas vehicles breaks down. You’re not going to be running a refinery in your back yard. Gas vehicles require a ton of infrastructure. It’s just much more widespread currently.

      Lets assume you’re doing 200 miles of driving each day (you’re the one insisting on using a full EV battery daily), that’s 2 days per gas refill. Assuming you’re siphoning gas from nearby vehicles (since there is no electricity to charge EVs or run gas pumps at the local station), you’re going to run out of gasoline very quickly in your local area.

      So while I can agree that day-to-day an ebike is decent transportation, assuming it’s safe to be outside in the sun for such extended periods. A gas vehicle is absolutely terrible in an apocalypse. An EV works well for decent range and will sure as heck get your further than going on foot.
