LOL! Seriously, where do you get that idea?
2020 is an outlier, an extraordinary circumstance, but any and all extra inventory will work it's way through the system.
The piece you quoted said "it had been estimated that international car sales were on track to reach 80 million in 2019"
The key word is
REACH. That does not mean all those cars have already been produced! Come on! You must understand that!
Plants have been shut down for weeks all over North America and all over the world. The global industry will not build 70 or 80 million cars this year.
You are conflating what was projected as if it has already been done.
Look...I was involved in the Automobile business, in both marketing and promotions as well as transport for over 25 years and during that time I saw just about all aspects of the industry, from manufacturing, testing, retail and the secondary market. I'm not going to sit here and spend an hour typing out a tutorial on how the auto supply chain operates, but please, take my word for it; No manufacturer could possibly stay in business if they built automobiles that didn't sell, and just sat in a lot somewhere, by the millions, as you seem to suggest, only to crush them and recycle them. It just can not and does not happen that way.
I don't know where you got this idea, but I have a sneaking suspicion. There was a Facebook meme that went around a while back, featuring numerous photos showing large lots packed with cars, one was even an airport, and it was suggesting that car builders just build cars willy nilly and park them, as if the whole industry is a scam. It was nonsense and utterly untrue.
Pictures like this for instance, were used to suggest that car makers are pulling a scam, and that they build too many and just park them;
When in fact, that is a photo of flood and otherwise
DAMAGED cars all from one event - Super Storm Sandy in 2012.
There are occasions where a particular model doesn't sell as well as hoped, and hundreds or even thousands of them sit at dealers or in shipping yards for sometimes in excess of a year. But even those get sold eventually, either through drastic markdowns or via the nationwide auction system, the latter BTW, during normal times in the US alone, handles MILLIONS of used cars a month, sold to dealers and then to consumers.
I'm sorry, but you are laboring under a misapprehension. The automobile makers of the world do not build millions of
extra cars that go unsold each year.
It simply
DOES NOT HAPPEN.
