Out with the gray dots, says Tesla ('bout frickin' time, we'll add) and in with this disclaimer:
"The map above is a representation of the corridors we plan to enable and the timing thereof. Exact locations and timing may vary."
We were certain this is what Tesla meant all along with those gray dots, but boy did something as simple as a dot on a map cause a lot of confusion.
Below you'll see a series of screenshots from Tesla's updated Supercharger maps. Gray is gone. All you'll see now is red.
Hat tip to kdawg!!!
