Earlier quoted context omitted.
I had to look it up but for reference in Q1 2021 the big auto makers delivered the following. Ford: 521,334 GM: 642,250 Toyota: 2.46 million VW: 2.5 million If Tesla holds up they'll be larger than Ford in 2 years and be the largest automaker in the world in 4 years.
Tesla has already lost marketshare in almost every market so they won't be bigger than Ford in 2 years. They will likely lose their regulatory credits some time this year because VW, Audi, Porsche and Ford have strong offerings.
Examples: IBM with IBM PC, Apple with iPhone.
