While I understand that public chargers expand the potential market for EVs, it just seems expensive and impractical. I imagine most people would only consider an EV if their family had multiple vehicles, with at least 1 of them being an ICE. I know I would never travel long distances in an EV, and would probably never use a public charger unless it was free. I don't like paying too much for trendy groceries though, so I would never encounter a place that offers free charging.
Unless DC fast charging becomes much faster, cheaper, and commonplace, I can't see public charging being sufficient for the common motorist. It's a shame that these DC fast chargers cost much more per mile of range than gasoline. It defeats a major reason why a common motorist might be interested in an EV. At home I'm able to charge at $0.02 / mile, compared to about $0.10 / mile in a 30 MPG vehicle.
My suggestion would be to steer people away from an EV if they would need to regularly rely on the public charging infrastructure.
