Lets Fire All the Traffic Cops!!!

It would be a very simple thing to add a simple transmitter/receiver, smaller than a beeper to every vehicle. It would constantly relay the position of the vehicle to receiver located in every lamp post. Cost would be like $5 a vehicle after ten years. The expense would be in the infrastructure of lamppost receivers and wiring a city wide traffic network and computers to process the data. In the long term is a hell of a lot cheaper than what you pay in property taxes to pay the salaries of traffic cops and meter maids.
Basically the result would be if you violate a traffic law you get automatic tickets. Everyone would naturally have a few free tickets, especially in the beginning. You can't break the speed limit for any significant amount of time. You can't make illegal turns. You can't park your car where you shouldn't. We can fire all the traffic cops and meter maids!!!! (Can I get a HELL YAH?).

Of course there is the drawback and that is we need to give up a little privacy but really how much would you care once you reap the benefits? One thing, there wouldn't be any need for car chases. The cops would simply follow from a great distance and wait you out. Probably let you go home and sleep it off, then knock on your door to arrest you in the morning. There would be no more stolen cars, it would be impossible to steal one. A computer would be able to spot seriously drunk drivers within minutes by how bad a person is driving and they can quickly be stopped from killing themselves or worse you. And all those bastards that cut you off and don't know how to drive will get their just rewards.

But surely you say something like this could be hacked and forged. Sorry nope. You see with enough resolution on the positional transmitters you can't forge a signal. There is no encryption or anything special. A computer knows where and when the last signal was to within about six feet. If you turn the signal off, that sends up a red flag. With every vehicle out there transmitting a signal, it's easy to detect the ones driving down the street without one. If you try to change your signal to look like someone else that's easily recognized, as that signal appeared in that location out of nowhere. It might be possible to swap signals but it would be simple enough to correlate all vehicles that get within an overlapping radius. Sure there would be minor issues at first but nothing too serious.

The reason this will never happen is that city governments and the police department make too much money off traffic fines. It has little to do with protecting the public and everything to do with paychecks.
