I go back and forth on traffic cameras.
They do seem intrusive and moving us towards a surveillance-state. BAD
They also seem effective in slowing motorists down and preventing motorists from running red lights (a particular pet-peeve of mine). GOOD
If the cameras didn't make money, they wouldn't be installed. If they cost a municipality MORE than they brought in, they wouldn't get installed. Since they bring in revenue, OF COURSE they are going to be installed.
Turnpikes have completely removed booths and gone to transmitters AND cameras. They mail motorists (or the license-holder of the vehicle, more accurately) a bill if they don't have an EZ Pass (for example) transmitter. This is not that different from traffic cameras. I haven't heard a lot of complaining about this use of cameras in a traffic situation.
That is one point that I had not thought of. I am assuming they don't mind it as it does not infringe on their ability to speed and travel as they please. Now if they did a SW update and added the speed camera functionality....
