The US Military is rushing 2,000 of these cheap green lasers to Iraq. I just happened to read the story right before seeing your post.

...Just simple green laser pointers. Having one pointed at you seems to be very effective at stopping aggressive oncoming traffic and personnel.... Troops obviously began experimenting, and discovered that even harmless, eye-safe laser beams pack a precision and intimidation value that works. According to field reports, aggressive driving has been reduced 60 to 80% when the devices are used. Along with the potential for tragedy.
