Tesla staff tracked Musk's relationships to anticipate his mood: Book

Several Tesla employees have said that they kept track of the company's billionaire CEO Elon Musk's personal life and relationship status in order to "anticipate" his mood, according to the book 'Power Play' by Tim Higgins. The employees claimed that when Musk was married to English actress Talulah Riley, he was "happiest" when Riley's hair "approached platinum" in colour.
