BTS. The Pussycat Dolls. "Scrubs." It's en vogue these days to make a comeback. Could Tesla's recently discontinued electric cars — the Model S and Model X — eventually join the trend?

On the podcast, Moravy said Tesla sold about 750,000 Model S and Model X cars during their lifetime. When asked directly if the Model S and
