With fourth-quarter earnings and the all-important conference call due next week, Tesla CEO Elon Musk appeared to possibly lower expectations late Tuesday with comments regarding key future Tesla products. Musk, in a social media post to X Tuesday evening, warned that early production for the Cybercab, which has been touted to be designed for true autonomy, and the Optimus humanoid robot will be slow. “The speed of the production ramp is inversely proportionate to how many new parts and steps there are,” Musk said on X. “For Cybercab and Optimus, almost everything is new, so the early production rate will be agonizingly slow, but eventually end up being insanely fast.”
