that scenario happened in my wilderness area of florida during the evacuation of hurricane irma 4 years ago...
i75 was a parking lot...
many drivers discovered the back roads in my area to avoid the traffic jam...
then the back roads became parking lots...
gas stations are at least 15-20 miles apart in some areas and further apart in others...
there are no charging stations anywhere once you leave the immediate areas of the major highway...
there were overglorified golf carts abandoned on the sides of the back roads...
and to top it off we didn’t have electricity for almost 2 weeks after the storm...
“and to top it off we didnāt have electricity for almost 2 weeks after the storm...”
We never lost power but all the gas station were empty.
Exactly my point!
