I think this here is the exact reason why we are all waiting for a single production model X to be made. If the line is the same as the MS line, they are probably going to produce one at a time for efficiency sake. I don’t know if in the past they were able to use a single line to produce both cars simultaneously, but possibly with supply chain issues, running it for one vehicle at a time makes better sense? They probably don’t have enough model X orders to justify closing the model S production.
