Configuration
| Setting | Value |
|---|---|
| Slice Type | lap |
| Metadata Only | False |
| Required Channels | throttle, brake, time |
When to Use
- User asks about pedal control or coasting
- User wants to know if they're maintaining car control
- User asks 'am I coasting too much?'
- User wants to improve weight transfer management
Key Options
| Option | Description |
|---|---|
lap_selection | all |
throttle_threshold | Threshold below which throttle is 'off' (default: 0.05) |
brake_threshold | Threshold below which brake is 'off' (default: 0.05) |
