Will petrol stations disappear?

With government policy moving swiftly towards the removal of diesel vehicles from our roads – probably a good thing, and eventually petrol too – and instead pushing everyone into electric and possibly hydrogen-powered vehicles, will I be able to find a petrol station in 20 years or so, to fill up my 1969 Rover P5B Coupé? As I understand it, the official target is zero emissions by 2040. What is the future for all classic vehicles if we can’t fuel them up and use them? Noshir Anklesaria, Surrey
