The focus on credits is interesting, but it should be noted that Tesla will produce twice as many cars this year as last and that they will have two new large plants producing cars before the end of this year (meaning that production capacity in 2022 could double again). My point is that a few hundred million in credits will not be the make or break issue that some are suggesting.
Also, my understanding of the credits is that they do not come from the government; they are negotiated contracts between Tesla and other non-compliant manufacturers. The 2020 credits that are being discussed are actually from a three year agreement with Fiat. So, Tesla will also receive them in 2021 in addition to any other credits that they negotiate. Honda recently agreed to pool their credits with Tesla, as well (in other words, Honda will also pay Tesla in 2021).
As I have said before, the credits are not some canary in the coal mine signaling Tesla's struggle to make a profit. I view it as an incredibly beneficial situation (for Tesla) that, essentially, has other auto makers paying for a big chunk of Tesla's growth and dominance in the EV market. Does anyone here, honestly, believe that a few hundred million will make or break Tesla in 2022?
