Uhm, that's no longer true. There's a lot of new charging stations.

This summer, I drove from MA to Washington DC and every other rest stop had chargers; sometimes multiple brands. I also drove from MA to Montreal and there were plenty of chargers.

Basically, every time I needed to pee there was a charger 5-10 minutes ahead of me. Plugged in, went to the bathroom, and then I had more than enough charge to go to the next bathroom.

There can be enough chargers without them being anywhere as prevalent as gas stations.

In this rural area, there's generally more gas stations near the chargers than there are plugs at the chargers (like within a 1/2 mile or whatever).

Depends on where you travel, I travel a lot in the west. Gas stations are not as common. I'm glad and not surprised to hear denser parts of the us are getting reasonable charger density as well.

... in the most densely-populated area of the country.

Within one mile of my house, I have access to 4+8+12+10+8=42 gas pumps.

There are 129 "public" chargers total in my metro area, and a decent number are at car dealerships (presumably mainly for use for vehicles left there for service) or hotels (overnight stays). I don't know how actually public the chargers are.
