Except that I fairly high percentage of California's utility power generation is solar. So that means you're trying to charge your own batteries at night when California's grid is lower on available power.
Good point. The MME has way more in common with a Model Y (or any EV) than it does with any other Mustang - three taillights and a vague resemblance on the front end.
I'm pretty sure EA has to negotiate locations and contracts separately with each individual state, and probably with each individual utility.
I would imagine that some states just haven't moved as quickly as others.
