Being within range of a charging station doesn't mean you can charge, it means you can get there. So yes, in a crisis, it means you could charge without risk of being stranded. But looking at most of the places I've been on that map, it would require me to go out of my way, often times an 1hr or more, to charge.
For gas this isn't a problem because gas stations are not just within a certain radius of me, they are on my route. But in your map, one of the towns I'm frequently in would require a 75 mile detour to charge, which doesn't really work.
Then after 3-4 hours of driving (200 miles with towing) you stop for 20 minutes to charge to 80% and continue on your journey.
