Summary

Story summary

The National Highway Traffic Safety Administration (NHTSA) expanded its engineering analysis of Tesla's Full Self-Driving (FSD) system to 3.2 million vehicles.
The inquiry targets whether FSD fails to detect visibility conditions such as glare or fog that impair camera performance.
NHTSA has linked nine crashes, including one fatality, to these issues.
The investigation will assess whether Tesla's degradation detection system alerts drivers when visibility is compromised and guide regulatory expectations.

History

Historical Context

The National Traffic and Motor Vehicle Safety Act, enacted in 1966, established federal safety standards for vehicles in response to rising traffic fatalities, which had increased six-fold since 1925. This legislation led to the creation of the National Highway Traffic Safety Administration (NHTSA), which now oversees safety regulations, including scrutiny of Tesla's Full Self-Driving system amid concerns over technology reliability in adverse conditions.
