Only test while parked or as a passenger. Requires location permission, HTTPS, and this page to remain open and active. iOS can suspend browser GPS in the background. This is NOT reliable whole-shift tracking or a tax mileage log. Version 2 filters for sustained driving-speed movement (three consecutive plausible fixes). It may miss real miles or still count GPS drift, especially indoors.

This GPS distance is intentionally separate from your odometer and shift earnings, to avoid silently double-counting mileage. We will compare results before integrating it.
