I wonder if Tesla is worried that this new model might cannibalize its more expensive, more profitable model S? Also, I should think that the level of automation required to produce a mass market car on the scale necessary to be profitable would be insane... And I bet Toyota, GM and all the others have patents on many, if not all of these production automation technologies.
For example, I would never consider dropping $90k on a car (unless I was earning many multiples of that a year), but $35k on a car that has the right range for me, and many of the mod cons of the grown up version? That's more likely.
Ask yourself this - why would anyone buy an A1, A3 or A4 when there is the A5, A7, TT and R8/RS8 from Audi? Because people want different things from cars.
