You arent suppose to drive with your fog lights on? I see that quite often, some folks drive with them on alone. Many look like the aftermarket kits you see in walmart. Guessing its a fad or gang thing.
Safety1st, the new chevy montecarlo is pretty good at being cloaked, but when you see a silver one with black hood, who do they think they are fooling. Also, never a bad idea to watch your behavior when you see a caprice or crown vic either.
There was a bomb threat near an office building where i worked right around 911. Man, you saw honda civics, vw jettas and many other cars you would never suspect of being outfitted with strobes and other emergency lights on location. I think many of those cars were for the other alphabet agencys.
