So if they were selling these engines in 2022 and 2023 this implies a transfer of funds from the seller to the buyer.  Where is the details of revenue from this let alone margin, costs and volume ?  It would be a start to transparency.  I also have to ask why they need to pivot to building the entire car ?  Can't they prove to us how profitable the engine business is before building the car...metaphors be damned.  If they really sold somethimg then why hasn't this been reported. ?
