Atlanta has an extensive deployment of fixed license plate readers which has gone mostly unnoticed. I think this falls into the categories of either not knowing or not caring, and I expect that to continue until there is a publicized misuse. For anyone interested, the largest deployment is in Buckhead, then Brookhaven, then Norcross. I have counted almost a hundred and fifty readers so far, and many more PTZ cameras.
Not to mention the rise of mobile readers, it's rare I see a Gwinnett or Dekalb county sheriff car without them. My local PD's newest car has hidden cameras and is always waiting along the most traffic-choked road, seemingly doing nothing... but actually waiting for hits on warrants and insurance violations. Apparently that is more lucrative than the traditional traffic enforcement for profit, as several acquaintances have had the misfortune of discovering on the way to my home.
Pro tip: Don't get busted for lack of auto insurance in Georgia, it is extremely expensive.
My understanding is that Georgia (specifically) also equips police cars with the ability to localize the position of many cars based on their RF "connected car" emissions at a range of several hundred meters, mostly higher end cars currently. These RF links will be in all cars eventually, it is regulatory (there is licensed spectrum dedicated for the purpose). Most people are oblivious to it.
