Musk regretted the discontinuation of the old Model X that year, and the impact still plagues Tesla today

Tesla CEO Elon Musk said on Twitter on Wednesday that the company made a "stupid" decision more than a year ago to suspend production of the old model when it launched the new Model X. The impact of this move on production still plagues Tesla.

Musk wrote: "We made a serious mistake in the production of the new Model X and have not fully recovered yet." "In December 2020, the demand is still very large, but it is stupid to stop producing the old X!" He said the Model X was very difficult to build, mainly because of the interior.
