Tesla's Cybercab robotaxi launched on 5 September and quickly attracted federal scrutiny. Investigators are examining the vehicle's lack of a 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 completed its first taxi trials, marking a notable moment 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 timeline for full commercial robotaxi service.
