Tesla's Cybercab robotaxi made its debut 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 dropped 6% after Wall Street described the update as underwhelming.
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 cast new uncertainty about Tesla's timeline for full commercial robotaxi service.
