I'm probably in the minority here but we bought our EVs privately with actual money. We've now had the Tesla for four years and the MG ZS for over three, and we are not planning on changing either car for some years yet. They both have battery and drivetrain warranties until 2027. Having had the Tesla checked over by an independent specialist, there is no major concern about the health of the vehicle or its systems, and on a plan for say 10 years of use it will be the cheapest motoring I have ever enjoyed. But we were primarily motivated by our CO2 footprint, and both cars are past the manufacturing payback point on that (dependent on the sources you look at, the MG may need another few thousand miles), so the next 6 years or so are all upside from that perspective. We have taken other carbon limitation actions, including installing solar (so in the summertime we can drive around for weeks on end, literally on sunshine), and far less showy things like massively improving the insulation on the house, lowering the thermostat a couple of degrees and looking at our diet (have gone more flexitarian). Some of these save money, others don't - but the motivation has been, within our limited circumstances, to try to "tread lightly"; I totally understand the choices individuals may make (ironically perhaps, I spent 17 years in the oil industry...), and also the sense of this being a mere drop in the ocean - but it is OUR drop in the ocean.
