Heres another way of looking at it.

If 90% of privately purchased cars in the UK are bought on PCP's and by 2030 you can not buy an IC engined vehicle, from 2025 ish onwards PCP residual values on IC engined vehicles are going to be horrendous and therefore in about 4 years time there will be pressure to take an electric vehicle, rather than IC engine.

4 years isn't that far off and there aren't currently many EV vehicles to choose from. If I was a manufacturer, I would be knocking out any EV variant I could dream up from my parts bin on the basis that demand will be high and supply will be limited. How many other large EV "estates" are currently available - none as far as I can see.
