Teslas can already charge at any standard electrical outlet or Level 2 charging station with adapters that come with the car and at any Level 3 charging station

Teslas can already charge at any standard electrical outlet or Level 2 charging station with adapters that come with the car and at any Level 3 charging station in the US with an optional CHAdeMO adapter, so it's more like they've set things up so you can fuel your Mercedes at any gas station, but they built a series of Mercedes-branded gas stations throughout the country that are cheaper, faster, more convenient and exclusive in addition to the standard network.
