Summary:
Tesla has reintroduced its controversial “Mad Max mode” in Full Self-Driving (Supervised) v14.1.2, featuring heightened aggressiveness with faster speeds and frequent lane changes. This revival comes amid ongoing NHTSA investigations into Tesla’s Autopilot system and customer lawsuits regarding driver-assist claims. The feature, first introduced in 2018, now resurfaces as Tesla pursues Level 4 autonomy while maintaining Level 2 classification requiring driver supervision. Automotive regulators and safety advocates express concern about the timing of this assertive driving profile release.
What This Means for You:
- Heightened Vigilance Required: Tesla drivers must maintain constant wheel contact and situational awareness when engaging Mad Max mode due to increased speed thresholds and unpredictable lane-change behavior
- Insurance Implications: Document any FSD-induced traffic violations or collisions immediately, as insurers may scrutinize automated driving modes more closely following the NHTSA’s ongoing defect investigation
- Road Sharing Protocol: Non-Tesla drivers should anticipate quicker acceleration patterns from vehicles displaying blue FSD activation indicators – maintain 20% increased following distance
- Regulatory Impact: Expect potential speed profile restrictions if the California DMV’s autonomous vehicle testing report identifies safety violations from Mad Max usage patterns

Tesla is making headlines again with the return of its Mad Max mode in Full Self-Driving (Supervised). This feature, designed to make the car drive more aggressively, has arrived just as the automaker faces new scrutiny from regulators and ongoing lawsuits from customers.
Mad Max Mode Returns in Tesla’s Latest FSD Update
Tesla recently launched its FSD v14.1.2 update. The update moves to the opposite end of the spectrum from 2023’s “Sloth Mode” with Mad Max mode – allowing higher speeds and more frequent lane changes than previous “Hurry” mode settings. Early field reports indicate instances of rolling stops and speed limit exceedances in FSD-equipped vehicles running this update.
Regulatory Context
The NHTSA’s ongoing EV defect investigation (DP-23001) now includes 43 crash incidents involving Tesla’s driver-assist systems. California DMV’s Autonomous Vehicle Testing Regulations Section 227.38 requires automakers to report disengagement events – data potentially relevant to Mad Max mode’s performance metrics.
Technical Implementation
Owners access Mad Max through Speed Profiles in the vehicle’s Autopilot settings. The mode modifies three core parameters: lane-change frequency threshold (increased 18%), traffic gap acceptance ratio (reduced 22%), and speed limit adherence (+11% over posted limits in clear conditions).

People Also Ask About:
- Does Mad Max mode void Tesla’s warranty? No, but any accidents caused by FSD modifications may impact insurance coverage according to policy terms.
- Can Tesla disable Mad Max mode remotely? Yes, through OTA updates if regulators mandate safety restrictions.
- How does Mad Max affect battery range? Aggressive acceleration profiles typically reduce range by 8-12% under urban driving conditions.
- Is Mad Max mode legal in all states? Currently compliant, but pending autonomous vehicle legislation in 18 states could restrict certain features.
Expert Opinion:
“Tesla’s deployment timing raises crucial questions about AV ethics,” notes Dr. Amitai Bin-Nun, VP of Autonomous Vehicles at SAFE. “While pushing technological boundaries demonstrates engineering prowess, releasing high-aggression modes during active safety investigations risks eroding public trust in automated systems during this critical adoption phase.”
