Quite a few have platforms that can accommodate GigaCastings. That takes planning...This. And having a bunch of profit weak models that overlap is a legacy issue. Going that route is counter to Tesla's philosophy. It's also not conducive to Giga castings. It's exactly the problem that the Chinese have who are trying to copy Tesla with castings are running into. How can one invest billions in casting when you don't have a single model that can scale to meet the required run rate to make the cost worthwhile, etc...
