But the choice here may be between buying a new electric and a used combustion that costs 1/4 of the price.
Or between buying a new electric and keeping the existing car longer.
Pretty sure that over the next 10 years at least, the latter two are the cheaper options.
This is why targeting new car sales, instead of fleet composition, is the best strategy. Despite the latter being the closer input to emissions.
ICE vehicles at and above EVs, in price and capability, should not have a market. Those EVs should then have the opportunity to decrease in price through both economies of scale and learning curves, on one hand, and the emergence of used vehicles, on the other hand.
The decision now is for 5-10-15 years.
The cost of replacing an old battery pack quickly exceeds the value of the car. You might be able to get a few extra years refurbishing it but that’ll be expensive and require niche battery work that’ll be hard to find.
This may well increase with electric cars being more reliable, but other failures (rust, collision) won't change much.
So 99% is too high. VEH1107 shows that 22.5% of cars in the UK were 13 years or older.

So there will always be more demand. It's the mainstream media that has it backwards: they're the ones always saying peak demand and that's misleading.
