From the Press Democrat comes an unnerving report that not only will your beloved GPS system guide and assist you while driving, but anything it says can, and will, be used against you in a court of law.

Most people don't realize the devices don't just supply info TO you, they store info ABOUT you as well. According to the article, "Among other things, these devices calculate speed and location, information that could prove critical in determining who is at fault in a car crash."

How do the authorities get this info? Usually by issuing a subpoena to the manufacturer. And there's a good chance they'll comply. (And thankfully little chance your girl will be able to get a subpoena to find out if you really were "playing cards with the guys" till 5am last Saturday night.)

It's not just GPS systems that are ratting you out either. The article goes on to say that "More than half of all new cars sold in the United States are equipped with event data recorders that investigators can use to determine such things as speed, braking and belt use in the seconds before and during crashes, according to the Insurance Institute For Highway Safety."

On the other side, the same technology is being used to help speeders beat tickets. The article notes, "Manufacturers of radar detectors are using GPS to download maps and warn motorists when they approach intersections where red light cameras are installed, as well as school zones or other areas where speed might be restricted or monitored." It's become a high tech game of cat and mouse on the roads.
