oh man i hope this catches on!! hopefully it will also ticket the motorcycle riders that think it's so cool to have their bikes deafeningly loud.

Great fun to stand below one with an airhorn and blast it as your 'mates' go buy.

Excellent I absolutely hate loud noises. Will this catch people who yell too loudly, or jaywalkers? How about people using colorful metaphors in public too.

its about time! something like this has been needed since the 80s when car sterios started to get rediculously loud. hopefully this'll catch on real quickly and we'll have alot less of those people who drive around thinking its cool to give people 5 miles away tenenitis.

I dont like automized law enforcement one bit.

There are a lot of drivers that fly through in my neighborhood that I would just love use an airhorn to get them ticketed. It's 15 MPH and people regularly go at least 40 MPH. Drives me nuts when they don't slow down even when kids are clearly playing on the sidewalks. No consideration what so ever. Would just love to inconvience them a bit.

I think a more effective response would be an all-out marketing campaign to convince teen males that blasting a car stereo is an announcement that you're gay and looking to pick up other gay males. Since an estimated 10% of the population is actually gay, I estimate a success percentage of 95% (taking into account a 5%-lesbian quotient) if this campaign were to prove effective. So spread the word: "Loud Stereo = Gay and Proud!" Look for it on Cafe Press.

Never will the residents hear the fading in bass as the car drives by, and the fading out as it leaves the scene of the crime.

Ok this may help prevent a minor nuisance, but there's really nothing more important we could be spending our money on? Why not use the money wasted on these things to hire more police officers so that we have people out on the streets to fight and respond to Actual crimes?? I agree with Rooster. I don't like automated law enforcement at all. And I especially hate it when the ONLY reason for it is to create revenue for the state.

All praise this tech!!! No iota, there is nothing more important we could be spending our money on.

We have a automated red-light ticketing system in place where I'm at in Minneapolis, MN. It would photograph people's license plates that ran a red-light and mail them a $150 ticket. It was just declared unconstitutional because they can't prove who the driver was. BTW - the hardware was leased at about $100M/year - revenue was less than that. I don't know stats on accident reduction etc... I would assume very similar results would be had with this sound recording/ticketing system.

Someone with more time and money than civic consciousness (and there are plenty of them around) will take this to the Supreme Court claiming their First Ammendment Rights have been violated. And they'll win.

I wonder if it's fast enough to record the sound of the shot from the sniper rifle.

For the 15mph zone guy - one person here took a mannequin, put dark blue coveralls on it, then decked it out with a reflective vest, and possibly a hard hat, then sat it in a lawn chair around a bend that drivers were going way too fast around for the street. Managed to slow down traffic and was legal since it wasn't impersonating an officer... Don't know how long until drivers caught on, though.

You might think, at first glance, that this technology is to stop people with annoyingly loud stereos. Not so. Like all 'auto enforcement' technologies, it is sold as a way to boost revenue for the local enforcement. They are advertised as bringing in many times their cost in tickets, and that is why they are purchased. Is that the point of law enforcement? As others here have said, as annoying as loud stereos may be, there are many more important things for us to focus our energy on.

"So spread the word: "Loud Stereo = Gay and Proud!"" How about: "Play It Loud = Gay And Proud!"

The airhorn idea a few people have already posted is just why these things will never hold up in court. Unless they have some crazy array of cameras and microphones that can localize sounds in 3D, there's no way of proving that a car is producing the sound being recorded.
