Automatic Collision Evasion

FSD (Supervised) v14.3.9

Automatic Collision Evasion activates Full Self-Driving (Supervised) to keep your vehicle safe and then continue driving. It can engage while you are driving manually and detects that you are not sufficiently attentive to the road (for example, reaching toward the back seat), or that Full Self-Driving (Supervised) may have been unintentionally disengaged.

See your Owner’s Manual for more details.
