Federal safety regulators want Tesla to spell out precisely how it will keep riders safe when its camera-only “Robotaxis” hit

Federal safety investigators have sent Tesla a detailed list of questions about its upcoming robotaxi service, focusing on how the company’s Full Self-Driving (Supervised) software performs in low-visibility conditions.

Federal regulators are pressing Tesla Inc. for details on how its driverless taxis will operate safely in challenging conditions as the electric vehicle maker prepares for a pivotal robotaxi launch in Austin next month.
