Tesla FSD Speed Profiles Explained: From Sloth to Mad Max | Taha Abbasi

Choose Your Driving Personality

Taha Abbasi has been testing Tesla FSD through every major version, and FSD v14.2 introduces one of the most requested features: granular speed profiles. The new system adds two profiles to either end of the spectrum, Sloth and Mad Max, giving drivers five total options for the first time.

The Five Speed Profiles

Sloth is the most conservative. Lower speeds, avoids lane changes unless necessary, prioritizes smooth predictable driving. Ideal for nervous passengers or school zones.

Chill was previously the most conservative option. Follows speed limits closely, makes lane changes only when clearly beneficial.

Standard is the default, representing the ideal balance between safety, efficiency, and natural driving feel.

Hurry pushes toward more assertive driving, taking advantage of speed limit tolerances and making more frequent lane changes.

Mad Max is the new top-end profile. Higher speeds, more frequent lane changes, and the most assertive driving style FSD has ever offered. Taha Abbasi tested this mode extensively and found it genuinely changes how the car navigates multi-lane highways.

How Driver Profiles Interact

Your driver profile now has a stronger impact on behavior. Tesla system learns from your driving style over time, and the more assertive your historical profile, the higher the maximum speed ceiling within the same speed profile setting. Mad Max for a conservative driver behaves differently than Mad Max for an aggressive one.

The Scroll Wheel Change

The right scroll wheel now adjusts Speed Profile rather than a precise mph offset. Scrolling cycles through the five profiles, making it easier to adjust on the fly. Taha Abbasi finds this intuitive for highway driving but notes some drivers may miss granular speed control.

Why This Matters for Autonomy

Speed profiles represent Tesla approach to solving one of the hardest problems in autonomous driving: matching human expectations. Different drivers have fundamentally different comfort levels. By offering five profiles, Tesla can satisfy the cautious grandmother and the impatient commuter with the same software. The data from these profiles is invaluable for Tesla training pipeline.
