im sure the deaf will feel it ,,, i know a deaf friend who couldnt hear one when she got stopped ,,,, but this device they are installing now ,, surely get thier attention ,,,as for others who say they can't hear it , must be half deaf too and should be able to feel vibrations ,,lol something ~~!!~i know i could hear one to scare the living daylights out of me while driving down road,, with or without music on ,, its a cool device for those who jam out thier stereoos ,, like those with amps that make sound louder ,, well now ,, they got something new that says ,, hear this ,,,!!! and you better stop ,,,

Of the fire, ambulance, and police, the police have always had a quieter siren. Not just here, but in other states to. If this makes it louder I guess it's good. Seems to me they would just use the same sirens as fire and ambulance, but I guess not.

I think it is a good idea, but not for the long run, it's not that good. Vibrations can destroy things like cars, homes, and etc. Look what the airport had to pay for homes do to vibrations. What about neighborhoods? Will it awake more people trying to sleep. Will it lower the Value of homes near main roads do to people not wanting to feel the vibrations. What about a person with a weak heart. It's scary enough and gets most people blood pumping hard when you get pulled over now.

This thing might work, but most of the time, it is'nt a case of not noticing the patrol car behind you, I think people are getting really brazen and trying to outrun cops, ignore cops and when they are in an accident, they just leave the scene, that is not due to being unconcious, that is just because the have no fear of the police.

Any thing to over ride that Thump music, that comes from some cars, what terrible sounds, is surely not music, this seems to be, why regular police whistles cant be heard. I dont care for Rhythm , impressionist, with no musical talent,some call rap.
