Four sites have opened, making four for the month and 160 total: Gardena, CA (off S.R. 258, surrounded by I-105/405/110); Blackwell, OK ( Jct. I-35/S.R. 11, just S. of the KS border); Bellmead, TX (Jct. I-35/S.R. 340, N,. of Waco); Genoa, OH (SE of Jct. I-80&90/280, SE of Toledo. Dual site due to toll road, currently westbound only, east-bound "Coming soon").
Although the I-80&90 legs east (148 miles to Girard) and west (169 miles to Mishawaka) are a bit long and need infill to shorten them (both are "Coming soon," in West Unity and Sheffield), the opening of Genoa makes it possible to drive I-80 all the way from NYC to Denver, a road distance of 1,780 miles. For now, you can shorten the leg between Genoa and Girard by detouring through Mansfield.
Blackwell shortens the 172 mile I-35 leg between Moore, OK and Wichita, KS to 107 and 66 miles.
Bellmead shortens the 202 mile I-35 leg between Round Rock and Denton to 83 and 120 miles, and makes it easy to reach DFW from San Antonio.
Gardena mainly boosts density, as it's fairly close to the other sites in SoCal, but it is closer to some of the freeways mentioned.
Per a poster on Plugshare at least one of the sites appeared on the EA map last night , but as I didn't check them then I'm calling them all May openings. Tomorrow marks one year since the first EA QC site opened, so 160 isn't too shabby, especially compared to Tesla's 27 or 29 over a similar period. Tesla's SC sites are generally better located, unless you enjoy spending time in lots of Walmart and Target parking lots, but that was the trade-off for the quickest possible build-out.
