Gas stations will be like the payphone, it'll still be around especially in rural areas. Gas stations that embrace the electric future like how Petro Canada installed EV chargers all along the Trans Canada will survive and offer all fuel that's in demand.
I would say urban gas stations are in danger as demand for gasoline and diesel dwindles. EV usage in town is different -- people charge at home, at work, or at play.
Side note, I find it funny that I buy transit passes as the gas station.
