**Summary:** GPS-fix wobble while the vehicle is stationary, accumulating ghost "distance".

- GPS drift is the wobble of the GPS fix even while the vehicle is parked.
- Over an 8-hour shift with several long stops, accumulated drift can add 1–3 false km.
- Professional apps filter drift by ignoring movement below 3 km/h or by leveraging accelerometer data.
- Unfiltered drift inflates receipt distance and can look like fraud in audit.
