In other words...
...buy your used car now before you get totally priced out of the market.
I'd love an EV. I really would. But until there's a really radical change in the economics I can't have one. My absolute outside hard-limit on spending on a car is a few thousand, but car ownership is really not optional. There is no public transport where I live at the moment. None. Nada. Zero. The nearest bus stop is a 2 mile walk away along a road with neither street-lights nor pavement. In the winter when it's dark that walk would be suicidal.
I'm not sure anyone has really taken into account exactly how necessary cars are for people who don't live in cities, and consequently how much many of us rely on extremely cheap second hand vehicles. Unless they're planning on banning the sale of actual petrol and diesel, it seems far more likely to me that this is just going to create massive upward pressure on used ICE vehicles.
