With all the horrible drivers out there and the fact that almost everyone I know has been in some kind of accident or fender bender in the past couple of months this little device might be a pretty good idea.
It is a combo camera, dvr, LCD screen and rear view mirror. It records all the action in fromt of you catching all the evidence if an accident or aggressive drive happens your way. Check out the car camera for more info or to buy this cool device.
