That only makes sense if that's Teslas goal. Considering they have spent years working for a cheap mass market car that's not their goal.
Neither is true.
The first is not true because Tesla's path is ever evolving. The end goal remains, accelerate the advent of sustainable transport/energy. But nowhere in that final outcome does it say anything about how much market will be ours. Sure, initially being the major market holder was not even on Elon's radar, but look where we are now.
Tesla's goal never involved a Gigafactory...ever. They did that because nobody else was.
Elon's goal was never to stay on as CEO of Tesla. That's changed now. He's not leaving the position as soon as Model 3 is massed produced. In fact he's changed his whole Tesla view and has publically hinted at making it a 'family' company (ala Ford).
Elon never talked about market evaluation for his company because that was never on the map. Now he mentions a way to a $1T evaluation.
Tesla confirming working on a semi. They'll definitely do Model Y, a pick up, another Roadster of some sort. That's a full line up and then some.
First we had Tesla, then we had Tesla Auto and Tesla Energy, now we have Tesla Auto, Tesla Energy, and Tesla Solar. And Tesla Michigan. And Tesla Germany. And Tesla Tilburg.
The list goes on and on and on.
The second is not true. The Model 3 is not a 'cheap' mass market car. It's a 'more affordable' mass market car. It's not an econobox car in anyway shape or form. And I doubt Tesla will ever go that route because compelling is a cornerstone of the brand.
I have no clue how this turns out, but I hope to be around to see it. I envision fireworks of epic proportions.
Rest assured the path to the end goal will change as needs be, including world domination/empire.
