San Francisco police officer Rich Lee vividly remembers the first time he tested the Rumbler in real traffic conditions.

It was a day when the manufacturer, Federal Signal, was in town to show off the Rumbler (or if you prefer, the Intersection Clearing System) to officials in various city departments and there was a photo session scheduled near the Golden Gate Bridge. It also happened to be budget week for the city and a day when the San Francisco police chief was at City Hall procuring dollars.

On his way to the Golden Gate Bridge for the photo session, Lee's BlackBerry alerted him. It was the chief at City Hall requesting Lee's attendance.

"I said, 'Can it wait 20 minutes?'"

The answer was no.

I like the idea of the Rumbler and because in this day and age it's hard enough to hear people talking to you in your own vehicle I would really like to have the Rumbler added to a "Home Alarm System." I think this would drive almost any intruder out of your house like lightening! Also for Home Alarms "High Intensity Strobe Lights" like those used at Airport Runways. I'd like to see a live demonstration (test) of the Rumbler, perhaps in a parade with advance notice to the audience of course.
