Tesla's Cybercab robotaxi made its debut on 5 September and immediately drew federal scrutiny. Investigators are examining the vehicle's lack of a steering wheel, which emergency responders say could prevent them from moving the car in a crisis. Tesla stock dropped 6% after Wall Street called the announcement disappointing.
On the same day, Turkey's Kaan P1 stealth fighter completed its first taxi trials, marking a separate milestone in the world's most crowded news day for anything on wheels. The Cybercab investigation and the stock drop have raised fresh doubts about Tesla's timeline for full commercial robotaxi service.
