I agree with much that you say, which basically expects all energy to rise, so transport costs of all types will be expected to rise. All these things have to be proportionate, for people to live and goods to move about. I therefore do not expect petrol/diesel to increase disproportionately in the future.. but then again what do we really know, the world is awash with oil, but also restricted by refining capacity. Saudi etc. will restrict supply to keep the price stable at a price they need, at present around 80 dollars. The other consideration is gas, which again is plentiful and a fraction of the cost of electric, together with an efficient distribution system that does not need massive capital funding.
I think much that we are planning in the West is wishful thinking with unrealistic goals, while India/ China will continue their own agendas.
