Tesla Inc. is in a sales slump, with deliveries of its electric vehicles on track to decline for the second full year in a row.

Tesla ( TSLA 0.04%) is one of the world's leading electric vehicle (EV) manufacturers, but many analysts believe the company's true value lies in its futuristic product platforms like the autonomous robotaxi and Optimus humanoid robot. In fact, CEO Elon Musk believes those products will make Tesla the largest company in the world one day.

The company has devoted resources to autonomous driving rather than developing new models to attract car buyers.
