Taking just Ford, they sold 1,995,912 vehicles in 2023 [1]; assuming it's divided evenly across vehicles, CEO compensation adds $13.25 to the price of a Ford. Probably CEO compensation is less substantial for a BYD vehicle, but it's just not a large component of the cost.

EDIT: Fixed the math, thanks mperham, I had $1.35 earlier.
