As many of have said, EVs work well for people with relatively short commutes who can charge at home. For that group of owners, the cost of charging at a Supercharger doesn't matter very much because we almost never charge there.People that live in apartments, condos, dorms, etc., or those simply traveling long distances may not have access to residential charging and will be required to use "super chargers". This will become more of an issue as electric becomes more mainstream. I don't know that it's fair to say it's inconsequential.
If I didn't have a place to charge (driveway, garage or at work) I'm not sure I'd want an EV.
As many of us have said, EVs make a lot of sense in specific situations. I don't think they work well everywhere for everything.
