Everybody uses GPS.
We already know that the positioning provided has an error, usually in the range of 4 to 10 meters.
That's about space, but what about time?
By using Torque we can estimate it.
Torque log files contains GPS coordinates and the speed calculated from GPS readings: we can try to relate it to the speed reading from OBD, that is instantaneous, while the GPS speed is subjected to the delay induced by the GPS itself.
