In fuel and tax savings it'll have paid for itself within those 3 years (versus a petrol or diesel car), after which it's effectively a free, zero-tax, zero-fuel-cost car.
My point being that an EV is already an absurdly good deal if you can make it fit your lifestyle. Also, I realize I'm biased, but I don't really get the range anxiety argument. If I run out of gas in a car I need to get towed to a gas station. If I run out of electricity I need to get to literally any wall outlet.
This adds to my thought that EVs will be a massive boon to the working poor. No more scraping the couch cushions for enough change to put in your tank to get to work, just go sit at a free charger somewhere. No more random breakdowns of a transmission, radiator, exhaust, etc. which can cascade into a lost job from missing work since you cant fix it. Once you can get an old used 20kwh+ EV for ~$1000 in decent shape, it’s going to be amazing for these people.
(this is what a tow service will do if you've only run out of gas)
You're right of course, although I still maintain plugging the car into a wall socket for an hour is easy to do almost anywhere - realistically this would get enough charge for most people to get to a charger (in my case it would get me to a rapid which would top up the rest of the battery in another 25 minutes).
A 1kWh battery is not big; e-bicycles carry ~500Wh.
Would be literally the electric equivalent of a gas can.
