The reverse scaling will be the problem more than the commodity price. As gas stations close, finding a refueling place will similar to what early adopters of EVs faced, but without the ability to do >90% of fueling at home or anywhere else the electrical grid reaches. Although maybe it'll become a thing for some people to store tanks of gasoline at their home. At that point I'd trade for a diesel vehicle, though, if I had a hard requirement of an ICE.
Farmers already keep tanks around to refuel at home. As do several of the other niches that I see as more likely to keep a gasoline car. If you live in the city you won't have a place to store fuel - but also won't need to since an EV is more likely to meet your needs.
