I'm sure they invited Tesla to participate. The company has a strong "not invented here" mentality. Tesla has their own network of proprietary superchargers that are incompatible with everybody else.
I have heard that either BMW or was it Mercedes.... Not sure, leaning towards BM'r, BUT one of them 2 has been working with Tesla on electric tech and Ellon allows anyone to use Tesla technology so won't be too much longer and we'll have MINI's that can do 0-60 in like 3 seconds :cornut:
