The 'our EV costs us nothing to run unlike all those ICE car driving mugs' need to check their privilege and also acknowledge that other people's mileage may vary (pun intended).
I was one of posters upthread who said the economics don't always stack up, due to the enormous extra cost of an EV (or installing solar panels for 'free' electricity).
I have a 3 YO petrol Skoda Citigo, I could buy a similar car today for about £9k. The same car in the EV version costs over twice as much.
I drive 6000 miles a year and my petrol costs me just under 15 p a mile so about £60 a month.
Call it 2 p a mile for the electricity, so £10 a month. Granted I have to pay £150 ish a year road tax and my servicing is slightly more, so call my petrol/servicing/tax costs an extra £700 per year over that of an EV.
But the purchase price of the EV is at least £9000 more. For the same car, more or less the same age. As I plan to keep the car for 10 to 15 years until it is effectively worthless, and you can probably assume the same for a 15 YO electric vehicle, £9000/£700 equals nearly 13 years before I've saved money on my 'investment' in an electric car. Even if a 15 YO electric car holds more value, which it could well do, then it's still going to me 8/10+ years before the EV starts to save me money.
Obviously the return on the investment will be quicker for higher mileage drivers, but its far from a given that an electric car will be cheaper to run for everyone, because for many it won't be. And that's before we add on the extra cost if you end up having to pay service station rates to charge them.
I agree that EVs are a money saver for people who do lots of miles in short to medium length journeys where they can always charge their car using discount electricity or that which is paid for by someone else (workplace or 'free' public charging) and for people who normally spend a lot of money on their cars.
But if you don't do a lot of miles, or conversely if you do infrequent long journeys where you need to charge while out, or if you don't have or can't afford solar panels (because that's something else that takes years for the investment to pay off) or you can't charge at home because you don't have a driveway, an electric car is far from a cheap option.
