In a few places near where I live there is extremely clear signage about the speed limit, and that speed cameras are in effect, 100% of the time, every single day. If you speed there, you will get a ticket. The systems are configured to only send the data of speeders, and are audited. It is extremely effective.
I prefer this system in every way to the way tickets are generally handled in the US. It's effective, it's fair, it does not discriminate against minorities, it does not endanger lives of the driver/police/other drivers as pulling someone over does, and it's much easier for me to avoid a ticket, it respects my privacy, persuasive / weeping / friends of cops can't get out of it, there's no chance for police to start tacking on other violations (your blinker is broken!)... etc, etc, etc.
It's just better in every way, except the fact that driving on these particular roads is really boring!
It's not just a neat tech hobby--this is a busybody pitching what amounts to ubiquitous rule-enforcement to the local government.
Saving the data for later mining, OCRing license plates to build a record of cars traveling around town, etc. would be a different story because that affects everyone whether or not they're choosing to break the law and spans more than a single incident in time.
1 - Do nothing
2 - Put a camera there just to get a % of cars going 5+ over the limit
3 - Put a camera there to OCR everything and save it in perpetuity
The distance between 1 and 2 is quite large but the distance between 2 and 3 is very small and doesn't necessarily come with the same public notice/disclosure/outrage instituting 2 would. The safest course of action strictly from a privacy perspective is to oppose anything that makes implementing #3 easier.More importantly, however, there are multiple forces driving deployment of cameras in a variety of area (e.g. right now my city is offering homeowners a tax benefit to install one because of an increase in crime, many people want all police activity to be recorded, etc.) and it seems unlikely that anything will reverse that trend. I think that means that the way to prevent abuse isn't to try to fight block the technology but rather to focus on legal protections & oversight – things like retention policies, restricted access and logging, etc. to avoid strengthening the argument that privacy activists are preventing legitimate police work.
