A word to the wise, if your going to do something as stupid as getting one of these transponders, you need to do a few things to your car. Firstly, make sure its beyond fast enough to outrun any police car, if not, rig it up so that you can completly destroy it from inside the car, say, a switch to blow it up or ignite something like thermite on top of it. And lastly, have something to flip over your tag when your stupid enough to go through an intersection doing this.

Mainly because a LOT of these busy intersections are recording when these things change them, and some are taking pictures of the cars that are doing it, or videotaping, and yes, these videocameras can see the IR beam coming from your car.
