Which is all well and good if A) an electric is an option and B) they suit your needs. For me it isn't and they don't and I can't really see either of those changing in the short to medium term.You are right it could be even bigger, as the government (whoever that is at the time) will be needing to ensure we are going to hit the proposed climate targets. So I'd imagine company vehicles will be highly disincentivised (sp/new word?) from taking anything other than a fully electric car, will also be in the wrong side of the decade to be going backwards.
My personal circumstances are in the minority though (small company, last company car budget was £15k with the car bought outright, must be an estate, lots of overnight stays away from home etc.) so I can see my personal finances being pretty heavily hit in the pursuit of "net zero".
