In my area there as been a single charging station I’ve noticed since we moved here (Houston) 10 years ago. I definitely do not see them popping up all over, but that is my location in the suburbs. Downton, things maybe changing.I have doubted it too, but times have changed, even within the last few months. If you are close to a big city in the US, they are accessible. Not as convenient as gas stations, but they are out there. My local grocery store put in 2, there are 4 by the hospital I work in, that went in over the last 4 months (these are on NYC streets).
In the US, I can agree that it may be hard to find in small towns, but realistically, in these small drive by towns, if you are there, you only need to charge from home, possibly once a week, or once every other week, since you never have traffic. If you commute far to work, as long as you are within the range of a charge, you can charge when you get home.
