Tesla's Cybercab robotaxi made its debut on 5 September and quickly attracted federal scrutiny. Investigators are examining the vehicle's missing steering wheel, which emergency responders say could stop them from controlling the vehicle in a crisis. Tesla stock fell 6% after Wall Street called the announcement disappointing.
On the same day, Turkey's Kaan P1 stealth fighter finished its initial taxi runs, marking a separate milestone in the world's most crowded news day for anything on wheels. The Cybercab investigation and the stock drop have cast new uncertainty about Tesla's plans for a widespread robotaxi rollout.
