GPS tracking units that you can fit to your car to track where your kids are
taking it (or *cough* other purposes) have been around for awhile now.  It's
interesting to see that recently the sorts of places that'll sell you card
skimmers and RFID cloners have started selling miniature GPS jammers that plug
into cigarette-lighter sockets on cars (general-purposes ones using internal
batteries have been around for awhile).  In other words these are specifically
designed to stop cars from being tracked.

(Some of the more sophisticated trackers will fall back to 3G GSM-based
tracking via UMTS modems if they lose the GPS signal, it'll be interested to
see how long it takes before the jammers are updated to deal with 3G signals
as well, hopefully while leaving 2G intact for phonecalls).
