Why invest 200 million USD to make 1 billion when you can invest the same to make 10 billion? The problem is that expanding isn’t free, you take the most probable business first. The low end is growing rapidly, but the players already there will ensure that Tesla doesn’t make $1k of profit per vehicle. They can’t compete with a Wuling Mini EV for $4k, or whatever BYD has up to the model 3 price point.
