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.

>They have things set up with super chargers to the point where it is as if when you bought a Mercedes you could only fuel it with Mercedes brand Roadtrip Gas when you needed to refuel on a roadtrip.

This is utterly mistaken.

You can charge anywhere, using a wide variety of chargers, ranging from very fast ones to electrical outlets (hopefully at least 220v because regular outlets are very slow), or even off the grid from solar if you're set up for that.
