And that has been Tesla's argument for the last ten years, yet they still lose about $9,000 on each car they make.
"On" each car, or "for" each car?
"On" makes it sound like their marginal costs are negative -- that, literally, producing one more car increases their losses by $9K. Were it "for" each car, then they're losing money only after fixed costs, R&D, etc. are taken into account.
That latter makes considerably more sense -- folks can legitimately decide to back a company investing in itself rather than taking out a profit; indeed, Amazon has done that for years.
