About Self-Driving Stats
Tessie provides a comprehensive look at how much you use Teslas Full Self-Driving (FSD) system. By integrating directly with your vehicle’s telemetry, Tessie captures data on when the vehicle is in control versus when you are driving manually.
Requirements
To enable Self-Driving stats, your vehicle must meet the following criteria:
- FSD v14 or later
- Firmware v2025.44.25.5 or later
- Direct Telemetry must be enabled
How to access Self-Driving stats
Tessie monitors your vehicle's automation state in real-time. This allows you to:
- Visualize trips: Select any individual trip to see which road segments of your drive were handled by FSD using color-coded routes and drive replays
- Analyze trends: Visit Drives > Analytics to track your FSD usage over weeks, months and years to see how your reliance on autonomous driving evolves
- Build API integrations: You can access autonomy data using our Drives endpoint or receive autonomy data in real-time using our streaming API
How to export Self-Driving stats
Follow the steps below to export your Self-Driving stats to CSV:
- Visit Drives

Self-Driving distance is listed under autopilot_distance.
Data precision & rounding
Tesla reports Self-Driving usage through a cumulative lifetime odometer that updates in 1-mile increments. This means the vehicle reports Self-Driving data when a full mile of autonomous driving has been completed over the vehicle's entire lifespan, rather than a full mile for the current trip.
To help ensure that you are fully credited for FSD usage, Tessie rounds up based on these "mile completed" signals.
Rounding examples
- At the start: If the vehicle reports a completed Self-Driving mile 0.5 miles into a trip, Tessie rounds up and credits the system for the duration from the beginning of the drive.
- At the end: If the vehicle reports a completed Self-Driving mile 0.5 miles before a trip ends, Tessie rounds up and assumes the system remained engaged until you reached your destination.
- Short drives: For trips under 1 mile, the vehicle may or may not trigger a "mile completed" signal depending on the vehicle's lifetime Self-Driving odometer. If Tessie detects a Self-Driving usage signal at any point during a short drive, you will be credited for Self-Driving for the entire trip.
This approach helps ensure that your FSD usage is fully credited in your analytics, even when the vehicle's internal counter hasn't yet reached the next whole mile.
