All companies have a mission, strategic plan and product roadmap, typically with a horizon of 5 years. We've all heard Elon articulate Tesla's mission is "To accelerate the world's transition to sustainable transport". He has further articulated the strategic plan (autonomous vehicles, gigafactory for cost reduction with scale) and a product roadmap to support that mission. Roadster as proof of EV concept Model S to build the brand to include a luxury family sedan Model X to extend the brand to include a family SUV/CUV Model 3 to further extend the brand to include a more affordable mass-market EV. True visionaries manage long strategic horizons, and don't feel constrained by an arbitrary 5-year horizon (e.g., SpaceX and Mars). I stumbled across this piece the other day, after the Model X founders' launch. There was a question from an analyst at the most recent conference call before the Model X launch along these lines, which Elon characterized as "insightful", but he declined to comment further. I find this speculation rather intriguing.
