Tesla Confirms It Will Not Restore User-Defined FSD Maximum Speed Limits

Tesla's AI lead Ashok Elluswamy confirmed the company will not restore the user-defined maximum speed limit feature in Full Self-Driving (FSD). Instead, the system will continue to rely on automated "Speed Profiles" (such as "Sloth" and "Mad Max") to determine vehicle speed and driving behavior. This decision highlights a growing tension in human-AI interaction, where drivers retain full legal liability for traffic violations under FSD (Supervised) but lack direct control over the vehicle's maximum speed. The mismatch between automated speed adjustments and driver comfort has led to increased manual interventions and driver dissatisfaction. Elluswamy described manual speed limits as an "anti-pattern," stating Tesla aims to train the AI to adapt to passenger preferences instead. However, owners report that these profiles behave inconsistently across software updates, with some experiencing standard mode driving too fast and "Mad Max" mode driving below the speed limit.
