The idea of cameras monitoring every highway, boulevard, and alley might strike some Americans as Orwellian. But even the American Civil Liberties Union acknowledges that the public has no right to license plate privacy on public streets. After all, cops can enter plate numbers by hand, so why not by camera? "There's absolutely no bar on collecting plates in public," says Barry Steinhardt, director of the ACLU's technology and liberty program. "There haven't been any legal challenges, because it's not illegal."
Yeah, you can flush your freedoms down the drain.......  
LA isn't the only place toying with machine vision-based traffic enforcement. Similar trial programs are under way elsewhere in California, as well as at city and state levels in Florida, Connecticut, New York, Ohio, Alabama, and Arizona. In Miami, as in LA, the systems are helping beat cops find hot cars. On Alabama's highways, stationary cameras are being paired with radar systems that automatically write speeding tickets as violators zip by. And in Sacramento, readers have tripled parking violation revenue by letting officers quickly spot autos with outstanding unpaid tickets (which they then boot).
Europe provides a glimpse of what even bigger deployments can do. In France, 1,000 mobile and stationary plate-reading cameras have doubled speeding ticket revenue and halved speeding-related deaths in just two years. In the UK, 200 cameras policing London's Downtown Congestion Charge Zone generated 13,000 arrests in one year. British law enforcement loves the technology so much that the government has plans for a $43 million campaign to install enough cameras to monitor every motorist on the country's highways, major roads, and bigger intersections, digitally reading some 35 million plates per day. This could catch not just every stolen car but nearly every moving violation as it occurs.
tripled parking violation revenue; doubled speeding ticket revenue...  Revenue and $$$ are the keywords here.   More money more camera's....  
Everything is going to be robotic ...  This artical was published in '05 I can just imagine what newer tech and better camera's can pick up these days.   Tho, I have mixed feelings about it.  Are we going to include face recognition next?  Well just mount camera's on all major intersections and everyone will be tracked ... And if you are suspected of committing  some sort of crime they will know when you went to the gun store or when you went to the landfill to dump the body.  Thats after they got you IP address from google that told them you've been running searches on how to kill people or dispose of the body.  
Big Brother is here like no tomorrow.  Orwell never thought about hooking the camera's up to computers that would relay the data over a network to populate where you have been ... your speed, your direction, time, etc...etc... into a big data base.   He also, didn't think of a huge wireless network that can track your cell phone ... Or even better yet, turn on your cell phones microphone and listen in your conversations or even track your computer at home while your searching through the biggest library on earth, all your thoughts and ideas are being traced through a huge network right back to you via IP address.  
It's a bit scary I'll say.  It's worse now then it ever was....   This is just the beginning.   Just think what they are gonna do with RFID!   Wait till they start putting the chips in all the bills (currency) that can be tracked right back to the owner to tell them not only who spent it but where it was spent, what was it spent on, what time it was spent and how much that person is spending...etc...etc....    
Good Luck!
Oh, and here is a link to that artical it's pretty interesting...
