Musk Warns Cybercab and Optimus Output Will Be 'Agonizingly Slow' Initial Ramp

Elon Musk said initial production of Tesla’s Cybercab robotaxi and Optimus humanoid robot will be agonizingly slow before capacity increases later this year. He indicated ramp-up timelines remain uncertain but expect acceleration once early production hurdles are addressed.

1. Tesla’s Autonomous Ride-Hailing Ambitions Face an Uphill Battle

Tesla plans to begin mass production of its Cybercab robotaxi later this year, with CEO Elon Musk envisioning a 24/7, fully autonomous ride-hailing network powered exclusively by its own self-driving software. To achieve that goal, Tesla must not only scale its manufacturing lines at Gigafactory Texas and Gigafactory Berlin to produce tens of thousands of Cybercabs annually, but also build a global digital platform complete with dispatch infrastructure, mapping servers and customer support. Unlike incumbents such as Uber—which boasts 189 million monthly active users and has partnered with more than 20 autonomous vehicle developers—Tesla is starting from scratch on both software deployment and fleet operations. Analysts note that while Tesla’s neural-network-driven Autopilot and FSD (Full Self-Driving) beta have already logged over 5 billion autonomous miles on public roads, translating that data into a reliable robotaxi service requires regulatory approvals, low-latency edge computing infrastructure and a proven liability framework that remains untested at scale.

2. Valuation and Financial Performance Under Scrutiny

Tesla’s top line shrank by 3% in the first nine months of 2025, driven by a 37% year-over-year decline in net income as production headwinds and price cuts weighed on its flagship Model Y and Model 3 lines. Deliveries fell to 1.636 million vehicles in 2025 from 1.789 million in 2024, marking the first annual decline since 2019. Meanwhile, Tesla trades at a stretched price-to-sales ratio of 16.1 and an extraordinary price-to-earnings ratio of 292, making it roughly nine times more expensive on a P/E basis than the Nasdaq-100 technology index. Investors and strategists warn that such lofty multiples leave little margin for execution missteps, especially given rising competition from legacy automakers and Chinese EV makers targeting the mid-market segment.

3. Early Production of Cybercab and Optimus Set to Be ‘Agonizingly Slow’

Elon Musk recently cautioned that the initial output rates for both the Cybercab robotaxi and Tesla’s humanoid robot, Optimus, will be “agonizingly slow” during their launch phases. Internal Tesla documents suggest that early Cybercab throughput could be limited to just a few hundred units per month as automated assembly lines, battery pack sealing and vehicle software integration undergo iterative optimization. Similarly, Optimus production is slated to begin at fewer than 1,000 units in 2026 before scaling to tens of thousands by 2028. Musk indicated that both programs will benefit from cross-learning between vehicle and robotics factories, but he emphasized that investors should expect a multi-quarter lag before significant volume and revenue contributions materialize.
