Although I don't consider it practical use, by my count opening of another 6 stations would allow the first transcontinental drives using only EA QCs. assuming max. spacing of 200 miles/leg, they would need the following sites to open to allow travel between the east coast from about Philadelphia southwards to W. Palm Beach, to Seattle or Portland (sites listed with an * are already identified as "Coming soon" by EA, with the specific location secured): Hermiston*, OR or Chubbuck*, ID; Salt Lake City*, UT; somewhere between Helper and Green River, UT; Grand Junction*, CO; Frisco*, CO; Geneseo*, Il.
Pooler, Ga is the key QC on the SE coast, and it can be reached from north and south over a wide area. From Pooler, you can travel through Georgia, Tennessee, Kentucky and either Indiana or Illinois by a variety of routes. From either Bloomington, Rockford or Woodridge, IL, you need a QC around Davenport (Geneseo) to shorten the leg to Williamsburg, IL below 200 miles [Note, there's a non-EA QC in Burlington, IA that could be used to connect Bloomington-Williamsburg now]. From there, it's a straight shot via QCs along I-80/76 to Denver, then west and north to SLC and either Portland/Seattle via I-84/82/90, or Seattle via I-15/90.
Adding another site in Ohio at either Huber Heights* (I-70/75 N. of Dayton) or Columbus*, OH, and another at either Girard*, OH (I-80 north of Youngstown) or else in Pennsylvania on I-70 somewhere between Washington and Somerset will allow much more direct access to the east coast from NYC to Washington. Three more around Columbia, MO; Independence*, MO, and Salina, KS, will complete I-70 from STL to Denver.
An additional two out west, around Wendover, UT and Reno, NV will allow direct access to Northern CA via I-80 from SLC. A further half dozen or so will also allow access to Southern California via I-70/I-15, and completing I-10 end to end will take 8-10 more. I-40 west of OKC will need another 10-12.
These are the minimum required QCs to make such trips possible, but until they increase the density so that max. leg lengths are no more than about 140 miles I don't consider them practical, and it won't be until they've reached their final goal of 70 mile avg./120 mile max. leg spacing that such trips will be easy and routine. At the rate they're going, though, I expect the first transcontinental route will be available by the start of summer; spanning the Rockies will likely be the key holdup.

Guy [I have lots of experience designing/selling off-grid AE systems, some using EVs but don't own one. Local trips are by foot, bike and/or rapid transit].
