I disagree with your implicit premise that Tesla has any significant compromises to be corrected. I enjoy driving Tesla vehicles more than comparable BMW, Audi and Mercedes vehicles. Most cars as fast as a Tesla look more like supercars, but they're smaller and less luxurious on the inside. And most cars as luxurious as Teslas internally are not as fast or have the same technology (to say nothing of the car being the best performing electric car).

I agree with your argument that few companies could leverage the needed resources to compete with Tesla on a comparable electric vehicle, but I strongly disagree that Apple would be the company to do it.
