I'm going to officially predict that along with the Model 3 reveal, Tesla will announce a change in sales strategy, moving away from the current model of online ordering and factory delivery, fine for a niche vehicle, to one of a traditional dealership/service center with an inventory of cars for sale. [...]
I also suspect the dramatic slow-down in supercharger construction and permitting this year is due to this impending strategy change, where dealerships/service centers/charging stations will be built instead of stand-alone chargers.
We will see if I am right in 9 days.
