Tesla's Cybercab robotaxi launched on 5 September and immediately drew federal scrutiny. Investigators are looking at the vehicle's lack of a steering wheel, which emergency responders say could prevent them from moving the car in a crisis. Tesla stock fell 6% after Wall Street described the update as underwhelming.
On the same day, Turkey's Kaan P1 stealth fighter finished its initial taxi runs, marking a separate milestone in the world's busiest news cycle for anything on wheels. The Cybercab investigation and the stock drop have raised fresh doubts about Tesla's plans for a widespread robotaxi rollout.
