Let's face it...the days of "privacy" are gone. Technology today can tell you where your girlfriend is..and with whom, what foods you purchase at the grocery store, and the red light you ran when you thought nobody was around..

If you're involved in a traffic accident with no witnesses except you and the other driver, it's just your word against his, right?

Wrong.

Your own car just might tattle on you if you're at fault.

So-called event data recorders that function much like the "black boxes" on airplanes, and which are now installed on virtually all new vehicles, can give investigators incriminating details about your driving behavior in the final seconds before a crash.

Some motorists -- fearful of what they see as an invasion of privacy -- aren't too happy about that.
