The Model S was “demoed” at the CES Nvidia booth (Tesla did not have a booth) in January of 2012 – about five months before production of the Model S started. I remember that the Model S was mobbed, overshadowing whatever separate PC graphics chip technology Nvidia was demoing.

Tesla’s robotaxi service has been mostly hypothetical so far, but it’s certainly taking the company’s shareholders for a real ride.

The company’s chief executive, Elon Musk, said this week that it would stop making the car, an electric pioneer in 2012, as well as the Model X.
