The Nissan Leaf is already the model T. It's been out 6 years, is affordable, and has DC fast charging. Besides my own, I see them every day here in Kansas City, along with the Model S.
Actually, because Nissan screwed up introducing the new model year of Leaf, in November there were twice as many Model 3s delivered in the US than Leafs.
It's unusual for Nissan to screw up like that, but there you go.
