Immaterial distinction.
When the product doesn't sell (supply > demand), OEM drops the listed price, or puts "cash on the hood", or subsidizes financing, or includes premium options for "free".
Whatever the method, the motivation is identical - improve value proposition by lowering the price, to nudge demand to catch with the supply.
The secondary outcome is an instant depreciation of value for all previously sold vehicles of the same type, current in the hands of (now less) loyal customers.
Please tell me that you are not THAT gullible.
Tesla manipulates prices to manipulate demand.
Nothing more, nothing less. Margins reflect that fully.
If you still think that Tesla does something to "pass economies of scale", please feel free to explain why it's "economies of scale" for Model X have been degrading from 2020 to 2023, before suddenly "improving" by 33% on September 1st 2023?
