2 years ago I bought an Audi that I was unable to get into after it dropped below freezing for the first time, because the window leaked water internally which froze and the door can't be opened unless the window comes down slightly. That doesn't mean the Audi was unfinished, or that all Audis are awful...
Shit happens, not every car is perfect, and i'm not saying it is, i'm just saying that they aren't selling half-finished cars. Defects are defects, not an incomplete product.
Having this many defects with this few cars made indicates serious production quality control issues, which just gets worse as production scales.
I would assume that defects will go down as they scale up, as things will become less manual and more automated, and they find the common problems and fix them at manufacturing time.
Are there other car companies that started from nothing that went a different direction? Did they start with nearly perfect cars then get progressively worse as they scaled up? Did they plan to mass manufacturer cars?
They don’t state in the article that the quoted facts about other automakers are for cars in their first model year.
Tesla's saying Tesla should sacrifice completeness because Tesla chose to sacrifice completeness. And a car with a bumper that falls off in the rain is in some way one of incomplete or unfinished.
