The tax credits may slow down EV sales in the short term.

this explains it. according to the article, many provisions of the bill starts at the end of the year regarding the $7.5k credit. however, one provision that starts immediately for the 7.5k credit is that it must be assembled in NA.
that link/table you posted is referring to this provision.
I don’t really understand this table. I assume it it reflects only which cars are eligible from the signing of the bill until 12/31/2022. But then why do they list Tesla and GM- they are not eligible as the 200,000 cap remains in place until end of year.
