Technology for parents to spy on kids

The San Francisco Chronicle has a great article on the rise of technologies for parents who want to spy on their kids: web-bugs, car-trackers, and GPS-enabled cellphones that covertly or openly spy on kids and rat them out to their parents:

Another company, Alltrack USA, offers a service that e-mails or calls parents if the car they're monitoring exceeds a certain speed or leaves a defined geographic area. DriveCam, which now installs cameras in fleet vehicles, plans to offer a monthly service to parents and teens next year that will let them watch video clips of their driving and receive coaching from driving experts.

CarChip-type devices differ from the "black boxes," or event data recorders, installed by manufacturers in many cars to record speed and other data in the seconds before a crash. A California law that limits access to that data does not apply to the types of accessories parents are using.
