Elon Musk is nothing if not ambitious, and his plans for the future Tesla certainly reflect that. Back in 2006, around the time Tesla introduced its first vehicle, Musk published the first part of his “Master Plan” for the company. It was certainly ambitious at the time, but it pales in comparison to the second part of his Master Plan that he published on Wednesday, nearly a decade after the first part was published. Whereas the first part was focused on building an electric car company, the second part is about expanding that company into a variety of other areas, such as manufacturing heavy-duty trucks and public transportation systems.
