No. A representative 45 minute trainer slog shows me moving .2 miles although I didn't actually go anywhere.
Google maps agrees with distance measured by wheel revolutions within the reporting precision of my Edge 500 - I got 11.77 miles when I mapped my commute on mapmyride.com, and the Edge displays 11.8 miles when I don't detour measured via the GSC-10 speed/cadence sensor.
