Being able to take SH 114 to US 287 via Wichita Falls & Childress to Amarillo and beyond on I-40 lops 2 1/2 hours off the trip through OKC. It's also the route Google Maps recommends between the Southeast and Denver, Albuquerque and points in Northern California, so I'd say a NE Tarrant County has some utility for long distance travel.
Since it would be the first North Texas Supercharger with Hotel, Shopping, Restaurant, Grocery and etc., I think it will be quite popular with people who don't have charging at home who would come once or twice a week, and long-distance travelers who don't want to stay at a Holiday Inn Express or eat at a Collin Street Bakery or Denny's.
