If HMG suceeds in getting all oil powered vehicles off the road, that tax loss will need to be replaced.
And we also have to consider what the oil producing countries will do too, it's been an imense earner for them for a long time, also there is still a lot of oil down there, I've seen estimates of enough for a 50 years at the current rate of use, are we just going to leave it there? I doubt it when the infrasructure is already in place and well understood, it'll probably just be refracted into diesel but no petrol.
