My feeling is that gong from a niche car maker to a mass car maker is not going to work.  Tesla can't seem to make a profit selling very high priced cars, and I don't think that economies of scale are going to work for them with the Model 3.

The big car companies who have billions of cash flow and years of experience mass producing cars, realize that electric cars are expensive due to the cost of the batteries.  Of course GM, Toyota, Nissan, etc can build a car at a lower cost than Tesla as they already have a lot of engineering work to draw from.  Tesla is going to have to spend billions to get the Model 3 built, and they will have no wiggle room. Tesla is hoping that by building a massive battery factory, they can achieve economies of scale.  If it does not work out, there is no second chance.

I don't see them meeting production targets, nor be able to sell the Model 3 for the expected $35,000 price point.  Investors will run out of patience at some point.
