Doug Field never considered leaving Apple. From the summer of 2008 to the fall of 2013, Field, a former chief technology officer for Segway and development engineer for Ford, oversaw product and hardware design, working on the MacBook Air, MacBook Pro, and the iMac. He earned a generous salary and was excited by the work. Then Elon Musk and Tesla Motors came calling, and Field agreed to become vice president of its vehicle program.
In the October 2013 announcement of his hiring, Field said joining Tesla was “an opportunity for me and many others to pursue the dream of building the best cars in the world—while being part of one of the most innovative companies in Silicon Valley.”
