Presumably a lot of people will charge at home which significantly cuts down the number of stations needed or the traffic to those stations.
For example, I have 2 gas stations within a mile of my home. They stay pretty busy because people around me constantly need to fill up. I, on the other hand, basically never visit either of those stations since I switched to an EV. I charge at home.
If everyone around me switched to EVs, those stations could not stay in business. There's a grocery store in the same area which makes anything those stations offer obsolete.
Those are the majority of gas stations that die with a mass switch over to EVs. There's a gas station for my hometown without an attached convenience store with 300 people there. There's no way that station stays in service if a significant portion of the community switches to EVs. It already struggles to be profitable as is (I know the owner).
That might be the case in places where most people live in single-family homes with dedicated garage.
Where I live (Spain) that's not the case at all - our towns are very dense. People in big cities tend to live mostly in flats (Europe's highest elevators-per-capita). Even people in the countryside, where it's more common to have a 1-family homes, often don't have a dedicated garage.
