Because you can't use them freely if you drive around.

There are dozens and dozens of petrol stations in my city, but when my tank runs low i only really go to "my usual place" that's near my house.

It's useful to have abundant stations in e.g. an emergency, but i assume most drivers refuel at their leisure.

It'd be like including your microwave in a map of restaurants in your area. Technically yes, you can get food there, but it's not the same.

It's an interesting part of the paradigm shift to EVs that one of the best things (refueling at home, cheaply, safely and greenly) is often discounted or even portrayed as a downside.

Similarly, in a parallel world where people only ate at restaurants, I can imagine suspicion about this new fangled home cooking, and how it's not a "real" restaurant, while the home cookers are like "it's cheap, convenient and healthy!"

Yeah, I definitely didn't mean it as a downside to EVs, just that home charging stations are private facilities, not public ones. The smear campaign to discredit plug-in charging (and its lasting effect on public perception) is one of the most annoying consequences of GM's attempt to get out of the old CARB EV mandate (before they just bought off some politicians or whatever they did to make non-plugin hybrids count as "EVs"). Witness the Prius being sold with "you never have to plug it in haha" as a selling point despite the fact that converting it to a plugin hybrid dramatically increases fuel economy. Gah.
