# Location, Location, Location

How about this for a challenge. Suppose you pay car insurance according to where you drive, as tracked every second by GPS – [see here](http://www.computing.co.uk/computing/analysis/2168742/insurer-takes-lead-gps). On the other hand, Transport For London (TFL) conclude that satellite tracking is not accurate enough to charge users according to where they drive – [see the report](http://www.tfl.gov.uk/tfl/downloads/pdf/congestion-charging/GPS-OBU-trials.pdf). The best results that TFL could get involve an error rate of 0.86%. So if your insurer mischarges you, how do you argue your case? Or put another way, if a customer disputes the data, how will the insurer be able to demonstrate its billing is completely reliable?
