The Model S was great, but their attempts to mass produce have been terrible and the quality has dropped significantly. The only advantage they have over other manufacturers at this point is range. Other EVs have long surpassed Tesla in the quality of their cars.

If they focused on manufacturing fewer cars and licensing their battery tech to other manufacturers they would be much better off. Instead Elon decided to essentially share the tech with competitors hoping to out compete car manufacturers who have been in the industry for decades longer.

I think they have now missed the boat on licensing the tech. 

The other companies are rapidly catching up and don’t have much reason to buy batteries. 

The chargers and getting a uniform location and connectors for the charger would be the next go to. As they still have a good advantage in charging infrastructure still.
