FSD (Supervised) v14 Lite

Model Y (AI3) Model 3 (AI3)

FSD (Supervised) v14 Lite includes:

Distilled the intelligence from HW4 V14 into HW3. This allows HW3 to directly learn how to handle scenarios using HW4 V14 as a guide. This process unlocks the improvements that have been made to HW4 including Reinforcement Learning (RL) and offline models for HW3.
Improved both proactive and reactive responsiveness across a wide variety of categories including navigation handling, merges and forks, pedestrian interactions, traffic lights, and vehicle cut-in scenarios.
Improved general comfort in nominal scenarios through fewer false slowdowns, smoother steering and more consistent lane centering.
Introduced unparking and reversing capabilities.
Introduced Speed Profiles to further customize driving style preference.

Full Self-Driving (Supervised)

Model Y (AI3) Model 3 (AI3)

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 Self-Driving Settings.

Speed Profiles

Model Y (AI3) Model 3 (AI3)

FSD (Supervised) will determine the appropriate speed based on a mix of driver profile, speed limit, and surrounding traffic.

Driver profile has a strong impact on behavior. The more assertive the profile, the higher the max speed.
Right scroll-wheel up/down will adjust the Speed Profile from SLOTH, CHILL, STANDARD, or HURRY.

Start Self-Driving from Park

Model Y (AI3) Model 3 (AI3)

A button will appear on the screen when driver requirements are met. Driver requirements include (but are not limited to):

Driver is seated in driver's seat
Driver is buckled
Cabin Camera is unobstructed

Brake Confirm requires the driver to press and release the brake pedal before FSD (Supervised) can be activated. You can also disable Brake Confirm in Self-Driving > Brake Confirm. When Brake Confirm is disabled, pressing the button will allow Self-Driving to apply the brakes and engage FSD (Supervised).

This feature does not make your vehicle autonomous and you must remain attentive and be ready to take over at any time. Only a licensed driver authorized to operate the vehicle should be allowed access to the driver's seat position any time the vehicle is not in Theater or Arcade modes.
