When Cybertruck winds down, it might have sold about the same number of cars as the Edsel. Though the US car market was much smaller then, so it would only have achieved around 1/5th of the market penetration. On the other hand, the Cybertruck is a cultural icon which the Edsel never was.
Tesla will be winding down production of the Cybertruck at Gigafactory Texas around the middle of next year to make room for increased Cybercab production
