<div>Furthermore, according to the radio interview I heard with a MoDoT spokesman, it's not tracking GPS, but what cell the phone is in. As your phone moves from cell to cell, it is presumed to be physically moving. However, the relationship between the two is not linear. The presence of various minerals in the earth or buildings between the phone and the cell towers, topography, sunspot activity, and probably even the phase of the moon will affect which tower gives a specific phone the best signal from moment to moment.

<div>If any government ever tries to use this for traffic law enforcement, it may be necessary for someone like EFF to send lawyers out to fight a couple of cases and set a precedent. And I only say that because of the reflexive presumption that police are correct in Marsupial Court.
