Now you are assuming electricity will be available in large quantities.
Of course I am. The number one way that America and the developed world consume energy in it's final form is through electricity. Hell, oil refineries are using an absurd amount of electricity as we speak. Do you think we're going to shut down the power plants and wind farms? In this post-apocalyptic, mains-starved world, where are you going to get gasoline?
I'm also not sure about lower operating costs. This year I visited some schools where teenagers learn to be a car mechanic. None of them where teaching about electric cars. Only one had a Prius but they didn't use it because of safety reasons. This means you'll need to rely on a specialist for servicing your EV for the upcoming decade while you can take your ICE car to the garage around the corner. I posted it earlier in this thread: the maintenance costs for an EV are higher than that of an ICE based car.
Not to be combative, but saying something doesn't make it true. Those schools ought to adapt, and soon, because nobody's going to need their graduates in 50 years when all vehicles on the road are electric.
I don't get where people get the idea that an EV has lower maintenance costs. It also has a gearbox, drive shaft, brakes, motor drive electronics and (usually) a cooling/heating system for the battery. It is not like an EV is less complex if you look at the entire car.
It's because EVs are less complex in terms of moving parts. Is an iPhone more complicated than a rotary phone? Yes, but its input electronics will probably last longer with no maintenance.
Do electric cars have any moving lubricated seals? Not outside of the transmission, if at all. Do EVs need catalytic converters, or emissions checks, or repairs on rusty gas tanks? Nope, because they don't have any of those. Do EVs need oil changes? Nope. Do EVs need replacements on anything in their engines, like gap seals, spark plugs, fuel injectors, fuel filters, or cylinder seals? Absolutely not. Do the brakes wear out rapidly due to acceleration and deceleration? No, because you simply use the motor to recapture kinetic energy and recharge the battery. I haven't met a single person with a modern EV who has had to replace their brakes at all, even in the mountains.
The mean lifetime of electronic circuits is tens if not hundreds of times longer than the mean lifetimes of mechanical combustion engine parts. The lifetime of brushless electric motors is hundreds of times longer than internal combustion engines for similar reasons; the maximum temperature anywhere is always <200C, there aren't any hot gases running anywhere, and there's little to no vibration or knocking of heavy metal objects moving linearly back and forth. There's simply less that
can be damaged.
