I'm not the argumentative type, so I'll say this once and won't follow any further.
Statistics are often misunderstood. This statistic, in particular, is basically saying that total OPERATING costs exceed the total revenue based on the number of vehicles sold so far.
Insofar as the operating costs will subside (i.e. superchargers will be completed and expansion of them will slow accordingly; the Gigafactory's building cost will be completed; and no doubt the batteries produced in-house will be cheaper than Panasonic's supplied versions), and the volume of cars sold will increase, this specific statistic ($x,xxx lost PER CAR) will, too, diminish.
And again, for the final time, Tesla did NOT lose $4,000 on my bosses's $142,000 P85D. Nor is $4,000 the 'average' loss per car. It's specifically a way of saying that the operating costs exceed the revenue, the value of which, when divided by the number of vehicles sold, equals $4,000 per vehicle sold. This is NOT a static number.
