Allows drawing a circle on GM for planning.
I found the exercise to be instructive. Assuming a 300 mile radius for the circle, there are very few places in the US that are more 'than a tank of gas away' from any given major urban area.
300 miles is used as a 'tank of gas' for most current generation autos. Oddly, YMMV applies directly in this case. :smiley_knipoog
One very disturbing US city at 260'ish miles distant (as the crow flies). Other than that, mostly water and a whole bunch of those loonie Ontario Canucks.
Just kidding, and no offense to any Canadian's here, if the SHTF at the Ontario / US border I'd expect it'd look something like this.

That is great tool. But remember that is as the crow (or Cessna) flies. It is possible to use a tank gas going 60 miles or less if traffic is heavy. That happened in Houston as well as NOLA during a hurricane evacuation.
I agree use the tool for knowledge but also if you are using it to do some bug out keep in mind you may need more than 1 tank of gas.
I used 300 Miles as that seems to be the 'magic' distance I see all of the time on the web.
Frankly, outside of bits of Nevada, you will find nothing that is not within the 300 miles circle of one or more ;major urban areas. East of the MIss river, refuges, (defined as outside of the deadly circle) just don't exist.
It makes for an interesting thought exercise if nothing else. I used this for writing the World of the Chernyi series.
I actually laugh when I read how some folks plan on heading to the woods and hunting to feed themselves. You and several million others have the same 'plan;.
In my 300mi circle I have Boston, Providence, Hartford, Augusta, NYC, Albany, Trenton, Philly, Montreal, Ottawa etc...I'm good. Right?
