Wright’s Law Predicted 109 Years of Autos Gross Margin, and Now Tesla’s
Ark Invest with another article on Wright’s Law.
I just skimmed it, but it looks like they’re misapplying it to Model 3. It seems they apply it to the entire vehicle based on the current number of Model 3’s sold ~300k. Technically many parts of a Model 3 (e.g. tires and windshield wipers) have been sold in the billions and therefore would not follow the same cost decline curves as the EV specific portion of Model 3. That effect has been mostly masked so far as the highest value portion of the cost was the EV specific parts. But as those rapidly decline with scale, the traditional bits will account for a higher portion of the total.
I believe Tony Seba made a similar mistake trying to apply battery cost decline curves to the entire vehicle.

@Doggydogworld had some criticisms and I would love his and/or any others’ takes on the article, or my criticism.
