Tesla Defines FSD Speed Profiles, Changes Default to 'Sloth'

According to the updated Owner’s Manual for update 2025.44, the 2025 Holiday Update, Tesla now sets the default Speed Profile for new vehicles and for those activating FSD for the first time to Sloth Mode.

Previously, vehicles defaulted to Standard; however, with changes to FSD v14, both Chill and Standard will drive above the speed limit. Sloth, by contrast, drives below the speed limit. The manual explicitly defines Sloth mode as “drives under the speed limit.”

Tesla has also provided definitions for each Speed Profile for the first time.

Default Speed Profile

The change to a Speed Profile that drives below the speed limit appears aimed at easing new users into FSD. If a vehicle begins driving above the speed limit, first-time users can become nervous, unsure when the vehicle will stop; the shift to Sloth can also reduce potential concerns with NHTSA.

This approach lets drivers build trust in FSD before trying other profiles. As before, once a driver changes the speed profile, that selection remains the next time FSD is enabled, allowing new users to start conservatively and remain in their chosen mode.

Speed Profiles Defined

The revised Owner’s Manual introduces concise descriptions of the Speed Profiles so owners better understand how FSD will behave in each mode.

• Sloth: Model Y drives under the speed limit.

• Chill: Model Y drives in slower lanes and makes minimal lane changes.

• Standard: Model Y drives at normal speed and adjusts speed to match the flow of traffic.

• Hurry: Model Y drives faster and makes more frequent lane changes.

• Mad Max: Model Y drives more quickly than in the Hurry profile, with more frequent lane changes.

Otherwise, the majority of the updated Owner’s Manual content related to FSD remains unchanged. These new descriptions add clarity to the Speed Profiles, which were previously only roughly outlined in release notes.
