Speed Profiles (part of 2026.4.5)
FSD (Supervised) will now determine the appropriate speed based on a mix of driver profile, speed limit, and surrounding traffic. However, the speed determined by the FSD (Supervised) may differ from the speed limit, and the driver is responsible for controlling the vehicle speed at all times.
- Introduced new Speed Profile SLOTH, which comes with lower speeds & more conservative lane selection than CHILL.
- Introduced new speed profile MAD MAX, which comes with higher speeds and more frequent lane changes than HURRY.
- Driver profile now has a stronger impact on behavior. The more assertive the profile, the higher the max speed.
- Right scroll-wheel up/down now adjusts Speed Profile setting rather than your precise max speed offset selection in mph/kph.

Full Self-Driving (Supervised) (part of 2026.4.5)
Under your supervision, Full Self-Driving (Supervised) can drive your Tesla almost anywhere. It will start from a parked position, make lane changes, select forks to follow your navigation route, navigate around other vehicles and objects, make left and right turns and park at your destination. You and anyone you authorize must use additional caution and remain attentive. It does not make your vehicle autonomous. Do not become complacent.
Full Self-Driving (Supervised) is enabled on your vehicle. To use the feature, press the Start Self-Driving button on the UI, or press the right scroll wheel button once. You can disable Full Self-Driving (Supervised) in Autopilot Settings.
