I didn't think much of the Apple Store suggestion when I first read it, but it is growing on me!
Here's what I picture: Apple stores with enough space (remember, has to be room for 3 cars, color swatches, etc.) get Teslas. If you buy one, it is contract thru Apple. Apple gets maybe 2% for offering the space and passing through sales. Tesla employees staff the Tesla space in Apple stores so that Tesla can control training and quality. This allows Tesla to shut down many of their expensive mall retail space, saving a ton. Also gets Tesla into ALL US States, as Apple is a "dealer". Tesla maintains separate service centers in all states.
There's only one major hitch to me: The Tesla UI is not Apple, and would be HUGE effort to convert. Apple would have a hard time doing this if their "religion" and product line is not part of the car. So, would only work with an immediate Car Play integration, and an "over time" commitment to migrate Tesla UI to Apple. Unfortunately, this comes with the baggage of Apple Maps as the map and nav core. Remember, Google (which is far more integrated with Tesla right now) is an Apple COMPETITOR!
Did I miss anything?
