>> If things remain the same
By definition, if EVs become dominant over ICE, things haven't remained the same. Gasoline is voluminous, and both expensive and difficult to transport and store. Electricity requires no volume or storage, and thus the need for a specialized "gas station" is mostly negated, as virtually anyone can offer it.
I imagine most workplaces will offer low-cost charging as an employee benefit, thus, most people will have the option to charge either at home or at work. How many drivers will still need to stop off at a gas station then?
