The supercharger network is now dense enough that you can drive anywhere in the US without worry. The largest gap in the nation is between Coeur d'Alene, ID and Superior, MT, and that's 100 miles. I've gone to rural Montana and Idaho in the winter and I've never had to worry about charging.

Also while Plugshare may show more dots on a map, that doesn't correspond to useful charging. Non-Tesla charging stations are notoriously inconvenient, unreliable, and slow to charge. That's why my friend with the e-tron rents a gas car if he wants to go more than a few hundred miles. This is borne out again and again in tests. When MKBHD tested a Tesla and a Mustang Mach-E, the Mach-E itself was fine but the charging infrastructure was unreliable.[1] The Mustang was delayed over 6 hours due to bad charging.

I've put almost 30,000 miles on my car and I've never had an issue with a supercharger. You just plug in and it charges. You don't need to install any apps or enter your credit card info. And if for some crazy reason I can't use a supercharger, I have adapters for the other connectors.

If you want the electric vehicle that can charge in the most places, get a Tesla.
