In general anywhere in the USA that is "on" an Interstate is solved problem for EVs. If you want to drive on I-whatever you're covered. The question above was about getting to remote areas far from infrastructure. And even there you need to work really hard to be far from a wall outlet.
Again, incremental costs to build out (non-supercharger) vehicle charging is much cheaper than installing a gas station, because it's ultimately just freeloading on the long-established electrical infrastructure.
Edit:
Do the downvoters really think the above scenario is acceptable? Being limited on where you can go, what chargers you can use and the increased time to go places?
If you're demanding to know that there is no where that your hypothetical gas vehicle is going to be an exclusive choice vs. an EV, then clearly the answer is no. Different vehicles have different capabilities.
And that includes your car! Do you normally get nagged by helicopter owners about all the places they need to be that your ridiculous wheeled thing can't reach? The whole thing seems a bit specious.
Generally you end up spending less time filling up in an EV than gas powered cars due to this kind of convenience. Filling up once or twice a week gets replaced with 2 or 3 fast charger stops on long trips and simply plugging in at home.
Are you writing a novel adaptation? This is how Heart of Darkness works. It... ends badly.
But sure: expeditions into the untamed metaphorical wilderness of the depths of the human condition probably do want to stick with ICE vehicles for now. But Tesla will probably get the savage wastes a supercharger soon enough.
Stuff is different. Different stuff works better in different situations. The point everyone is making is that long road trips and access to very remote locations are definitely not the sweet spot for an EV, but they're tasks it's capable of doing well enough.
Seriously if you desperately want to do your crazy day trip where you drive for 9 hours, and you own an EV... just rent a Jeep or an Outback.
If that’s not enough for a day trip I have questions. IMO, even traveling that range for a weekend is questionable.
However, the long range Model 3 only does 353 miles without charging. But you’re adding ~175 miles in 15 minuets, which is where I was getting the 530 mile figure. Basically 400+ miles is where charging wait times become noticeable.
Of course numbers depend on driving habits etc, but that’s the rough ballpark.
My dad & I have done driving around Bears Ears, Grand canyon, various national parks & forests in Colorado & Utah, and have basically had to roll downhill into Loa (if I remember the town right) when we were at the bottom of a tank.
Blanding, UT surprisingly shows a tesla supercharger, but Monticello doesn't. So I imagine the overall situation will get better over time too.
Sorta another side question - I assume any sort of car-hauled solar is too weak to meaningfully charge a car? Totally back of the napkin math (80kwh battery @ 200w portable solar = 16 days to charge). Obviously a partial charge could be had quicker, or a larger solar setup, but not really feasible, even if you figure out all the connections.
In Utah and Wyoming you can be on the interstate and still be far from a gas station[1]. I don't think most people who don't live out west are aware of how remote parts of this country truly are.
