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.
