U.S. Regulator Probes Tesla’s ‘Mad Max’ Mode Over Safety Concerns

The National Highway Traffic Administration (NHTSA) is investigating Tesla's new "Mad Max" driver-assistance mode amid concerns it allows vehicles to exceed speed limits, intensifying existing regulatory scrutiny of the company's Full Self-Driving (FSD) system. This inquiry adds to ongoing probes into FSD's safety record, which includes numerous reported traffic violations and crashes, potentially leading to further regulatory actions, recalls, or restrictions that could impact Tesla's FSD deployment and market perception.

Analysis

The National Highway Traffic Safety Administration (NHTSA) has initiated an inquiry into Tesla's new "Mad Max" driver-assistance mode, citing concerns it allows vehicles to exceed posted speed limits. This action intensifies existing regulatory scrutiny of Tesla's Full Self-Driving (FSD) system, which is deployed in approximately 2.9 million vehicles and includes the "Mad Max" mode known for faster speeds and more frequent lane changes.

This latest probe follows the Department of Transportation's documentation of 58 FSD-related incidents, including 14 crashes and 23 injuries, linked to violations like red-light running and wrong-way driving. Tesla has a history of regulatory challenges, including a 2022 recall for a "rolling-stop" feature affecting over 50,000 vehicles, underscoring ongoing concerns about its software practices.

While Tesla indirectly defended its Autopilot system's safety record, reporting a Q3 2025 crash rate of one per 6.36 million miles compared to a U.S. average of one per 720,000 miles, the persistent regulatory pressure (TSLA sentiment: -0.75) suggests potential for further recalls or restrictions. These ongoing investigations could impact FSD deployment, market perception, and ultimately, Tesla's valuation.

Key Decisions for Investors

• Investors should closely monitor the progression of NHTSA's inquiry into "Mad Max" mode and broader FSD investigations, as regulatory outcomes could significantly impact Tesla's operational flexibility and FSD revenue potential.
• Evaluate the potential for increased recall costs, fines, or restrictions on FSD feature deployment, which could pressure Tesla's margins and slow its autonomous driving roadmap.
• Consider the reputational risk associated with ongoing safety concerns and regulatory scrutiny, which may affect consumer adoption rates for FSD and overall brand perception.
