The article misattributed the source, it may have technically been my post that they learned it from, but it was originally pdeinselen's find. I was just copying it from the general Florida Superchargers thread into the specific one for Clearwater so that proper discussion of the location could all be in one place.
And, I don't know what Electrek is smoking, but there are way more confirmed V3 locations than just 4. There's probably more than 40 that are known to be in construction or permitting. More than half of those are along the Trans Canada Highway, but even just in the US there's a bunch.
