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.

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.
