Tesla’s lead engineer had taken a leave of absence for “several weeks.” This engineer, Doug Field, is responsible for overseeing vehicle development. Tesla said: “Doug is just taking some time off to recharge and spend time with his family.” Field leaves during a time of struggle for Tesla, where they cannot keep up with the demand for its Model 3. Selling the Model 3 is key to convincing investors that Tesla vehicles are appealing to the mass market.
