Tesla is winding down Cybertruck production after years of poor sales in a handful of markets. The truck never delivered its promised $40,000 starting price or 500-mile top-spec range, and its stainless-steel exoskeleton idea gave way to a costly conventional unibody with difficult-to-work stainless panels. Commenters argue the delays and wasted effort came from ignoring engineering expertise, and that Tesla could have built a simpler, cheaper electric pickup years earlier.
