Such a cool question! My perspective as a Lithuanian:
I think they will continue to sell both petrol and diesel in 15 years. I think gas (we have some cars running on literally gas) will not be there anymore. There will be more EV chargers, I would think in every station.
I would think in 15 years someone will try and succeed to create a "destination gas station", like a cool restaurant, that people will go out of their route to visit.
I don't think we will be on self driving trucks in 15 years. But once we get there, gas stations will service them in whatevet service they will need.
