New police siren

I saw a story about this on the noon news. The new sirens use flashing lights and vibrations. It could help police with Deaf drivers and folks who have their radios blasting.

that was old news. very old news. I think it appeared in Popular Science or somewhere couple years ago. I thought this was interesting but IMO - it's more of an annoyance. This was especially designed for drivers with loud radio blaring or yapping away on cell phone.
