Investigation Escalation
Ever wonder why Tesla's ambitious Full Self-Driving promises hit roadblocks in fog or rain? The National Highway Traffic Safety Administration is digging deeper with an expanded probe into FSD's handling of poor visibility.
Tesla vehicles equipped with FSD rely on cameras that trigger a degradation alert when conditions obscure the road, supposed to hand control back to the driver seamlessly. But does it always work as intended?
Engineering Analysis Phase
NHTSA's Office of Defects Investigation has moved to the engineering analysis stage—the final step before considering a recall. This examines if FSD's safeguards hold up when visibility plummets, like in heavy rain or dust storms.
Reports from Reuters had flagged initial concerns, prompting this deeper scrutiny into camera-dependent autonomy.
Core Concerns
- Camera clarity thresholds in adverse weather
- Reliability of driver takeover alerts
- Potential for undetected degradation leading to unsafe operation
- Path to recall if defects confirmed
