Teslas sept 2023 q3 operating margin was 11.18% and peaked at 16 before all the cuts. This is while ramping 2 factories.

BYDs latest seems to be 5.33% and peaked around 9.5 in 2018 and has been under 8 since. I don’t know what BYDs factory ramping situation is.

Ford for the past couple years has hovered a little above and below 4. Was worse further back.
