I think you completely, deliberately misunderstand.
Your inventory statement applies to the old guard, ICE dealers, and their method of doing business: build first, sell later (and use as many nefarious tricks as you can to snooker customers). Tesla's method, sell first, build later currently has a logistics difficulty but that will be sorted through. It's better for Tesla because the cars have already been bought.
I do admire your patience, on the one hand; it's something I don't have much of and would probably be better off with more. On the other hand, your constant misinformation and spinning is tiresome.
