What would the math look like to make an EV cheaper than using an ICE car you already own? It looks an awful lot like you're just dodging the numbers yourself.

Okay, for even a very basic EV I'd be paying £400 per month.

This is more than the £200-300 or so it costs to run my existing car.

Straight off, it's costing me more just to even own one - that's before it turns a wheel.

Tax on an EV is free just now, and about £300ish a year for the vehicle I have now, so that's got the difference down a little.

Insurance on even a fairly basic EV would be a couple of hundred quid a month, as opposed to a couple of hundred quid a year. This immediately makes running an EV uneconomic.

At the end of the five year lease (you can't buy them outright, without getting entirely ripped off) I'd have spent 24 grand to still not actually own a car. This is roughly 100 times as much as I spent to actually own a car. This too makes things uneconomic.
