To be considered successful, most companies need to sell more of their existing products and/or introduce new products. Tesla is doing neither – they have reduced the number of models they sell and are also selling their existing models in lower numbers.

I mean it's really TBD on what happens with Cybercab. The X and S models were always low-volume, and it makes perfect sense to move on from those models.
