Tesla Faces Deeper Scrutiny After Fatal Crashes

The U.S. National Highway Traffic Safety Administration (NHTSA) has intensified its investigation into Tesla's driver-assistance system. The probe now encompasses approximately 3.2 million Tesla vehicles across multiple models, a significant expansion from its initial review. This action stems from concerns raised by nine crashes linked to the technology, one of which proved fatal.

Regulators are specifically examining the system's capability to detect when conditions degrade visibility, such as glare or airborne obstructions. The NHTSA is questioning whether the system, including its software updates, adequately warns drivers to take control. This development underscores increased regulatory scrutiny of Tesla's self-driving technology.

Available data suggests that if a recent update to the degradation detection system had been installed at the time of the crashes, it might have impacted three of the incidents. The agency's analysis indicates a potential failure of the system to recognize reduced visibility or provide timely alerts, raising concerns about its overall safety performance.
