Isn't salary an expense? You need to sell a 100K car with 25% GM to "make" 25K. So, if he is paid 800K to 1MM, that is 40-50 cars and more (health care, options, perks, travel expenses). Then he hires his "team" from AAPL and other friends.
Let's say he gets paid 500,000 a year. Car companies on average make 1000 dollars net profit per car sold. For instance Ford makes 5 billion dollars a year selling 5 million cars. So, (even though Tesla still loses money per car sold), if they make 1000 dollars profit per car, they will need to sell 500 cars more a year to make up the salary.
The last proxy shows Blankenship as the highest salaried officer at $344,500/year. Most of Tesla executives' compensation is in option grants. Causes dilution, but no profits, no dilution. Helps Non-GAAP "earnings."
