This is been tried to varying degrees and failed.  It&#x27;s really difficult to get the major players to work together.<p>However, I&#x27;d say that VW is probably the closest analog.  Their car platforms are largely LEGO-like components that can be put together in varying configurations as needed by their different product lines.  They have a handful of major platforms that underpin the majority of VW, Audi, Porsche, Seat, Skoda, and Bentley, and they are working on unifying Lamborghini with Porsche and Audi.<p>I know it&#x27;s not what you&#x27;re envisioning, but the reality of manufacturing places limit what can be done.  Tesla is such an insignificant player right now that what they are doing manufacturing-wise is not yet relevant to the industry at large.   They sell thousands of cars a year while the major industry players all sell millions.  Tesla can survive with inefficiencies that would destroy Toyota.
