of gps reliability. Many are actively promoting gps tracking devices designed
to record driving behavior and reward safer drivers with lower premiums.
The Bell on the Cat
While some drivers lost patience with their navigation devices, many others
were losing the units themselves—to thieves. As sales rose, so did car burglar-
ies. The fbi reported that gps thefts from vehicles jumped 30 percent between
Bethesda, Maryland, police echoed an admonition to car owners that was prom-
inent in gps-related theft stories: leaving suction-cup mounts on car wind-
decreased. Drivers may have learned to be more careful. More likely the decline
is because gps navigation has migrated to smartphones, which people tend to
take with them when they leave the vehicle, and to a growing number of in-
dash systems, which are less prone to “smash and grab” break-ins. Industry
analysts predict factory-installed navigation systems will overtake pnd ship-
ers programming their address into gps systems as “home.” A car thief drove
his victim's Lexus to her house, used the garage opener to let himself in, bur-
glarized the home, and abandoned the vehicle nearby.

When thieves steal pnds, the odds of recovery are slim. Stolen or lost smart-
phones are another matter. The gps infrastructure by itself cannot track receiv-
ers using the signals; tracking requires additional circuitry to transmit the
calculated coordinates to some other monitoring system. As discussed in the
preceding chapter, that technology is built into phones to meet the fcc's man-
date for locating mobile 911 callers, and it has migrated into tablets and some
laptop computers. It enables apps that owners of stolen or lost smartphones—
