> since there are gas stations all over
That's the assumption, though. There aren't. There is an illusion of it, sure. I gave that anecdata from personal experience. It isn't "ridiculous", it's called having lived (and learned to drive) in rural Ohio.
Well, I've lived for several decades in several different states/regions, and in my experience, gas stations are all over. They even have signs on the highway when there's no gas for x miles ahead.
While there may be electricity everywhere, there certainly are not high-speed chargers in places where gas is even close to scarce.
Can you install it in your garage? Sure, if you've got the panel for it. But that's beside the point when we're talking about refueling on trips. That is, and will be for the foreseeable future, faster in an ICE. That's why we have PHEVs. Maintenance may be higher than an EV, but they're much better on road trips.
If the region is so remote that gas station access is really that poor, ev charger access is probably entirely nonexistent.
But electricity is not nonexistent. It's easier to run an EV in rural Ohio than a gas car because you can install a real nice charger in that huge garage you have or outside your big barn next to your gravel lot, whatever, you've got space and a grid connection. That's not currently the average mentality, but that returns us to the sociopolitics of rural Ohio and EV adoption in the US in general more than any of the technicalities.
