I live in the Nevada high desert 180 miles from Twin Falls, 258 miles from Boise, 244 miles from Salt Lake City, 304 miles from Reno, and 437 miles from Las Vegas.
So NO. EVs aren't ready for primetime in the rural US.
However, one of the race vehicles in last year's Dakar Rally was an EV with a 4-cylinder motor under the hood turning an alternator to recharge the battery while rolling. The combination simplified the driveline and extended the range. That kind of setup might work, but battery technology remains the limiting factor for now.
