I used to run analysis using the US road network and the list of charging stations. A year ago, the longest stretch of roads without high-speed chargers was Montana to North Dakota, with 220 miles. The next one was in Oregon, something around 180 miles. More than 99% of the named locations reachable by numbered US highways and freeways were within 100 miles of a fast charger.
So technically, if you did even a bit of planning, you could reach ANY point on the public US roads and still have energy to drive to the next charger with a car having around 350 miles of range. With just 20-30 carefully placed stations, you can cut that down to about 250 miles of range, well within the current capabilities of EVs.
I eyeballed the map, and it looked like around 200 additional fast DC stations would put _any_ reachable location in the lower 48 states within 50 miles of a charger. This is the endgame for the range anxiety. And even at $1m per charger, it would cost less than one day of funding the military. Heck, even at $10m per charger it would still be less!
