I want you to try and engage with the deeper idea, here. You are so indoctrinated in the fossil fuel industry's talking points and fear-mongering, you don't even have a clear frame of reference to think about the issue.

What is preventing ANY electric car from plugging in to electricity ANYWHERE?

An extension cord.

What is preventing a gasoline-engined car from refueling ANYWHERE? The limited availability of gas from only certain locations that are authorized to store and sell this extremely dangerous material called gas.

Yes, the problem is more complex because the electrical grid in America is a shambles and was never designed to ... well, honestly, it was never actually designed ... it just grew as need grew.

With an intelligent infrastructure plan in place that modernized our electrical grid, electric cars could be a critical part of the infrastructure and plan, and play an important role in storage of non-fossil fuel energy for off-hours consumption.

Which brings me back to the 300 miles thing you chose to ignore, to keep spouting fossil fuel industry FUD that you have been successfully indoctrinated with ... the vast majority of Americans - something like 70% or more - don't drive 300 miles in a WEEK. So regardless what type of powerplant you have in your vehicle - an EV or ICE vehicle with approx 300 mile range between "fill ups" of either electricity or gas - which one is MORE LIKELY to find its "fuel" literally anywhere?

The EV. Electricity is far more ubiquitous than gasoline, and all you need is an extension cord. No tanker trucks. No fuel tanks buried underground leeching toxins into the environment. No exhaust fumes. No oil refineries. No oil rigs toppling over in bad weather, or oil tankers crashing into Alaskan beaches. No wars for oil in places where brown people live. No more money flowing to Saudi Arabia or Aramco.

All of that can be eliminated with a few (metaphorical) extension cords.

See what I'm driving at here...?
