Elon Musk 2016 … (my bold)

The first master plan that I wrote 10 years ago is now in the final stages of completion. It wasn’t all that complicated and basically consisted of:

  1. Create a low volume car, which would necessarily be expensive
  2. Use that money to develop a medium volume car at a lower price
  3. Use that money to create an affordable, high volume car
  4. Provide solar power. No kidding, this has literally been on our website for 10 years.
