A company called Leonardo already develops and sells automatic license plate readers (ALPRs). These are cameras that visually see your vehicle as it drives by, recording your plate for any number of reasons, though probably because you ran a red light or missed a stop sign. Now, it seems the company has plans to go a little further.

 

It's not an optical upgrade, though. There are plans to add sensors to its cameras in the form of an "advanced signal intelligence system." As reported by 404 Media, ELSAG SignalTrace is a system that sweeps up unique identifiers of electronic devices that give off signals. The idea is to track or identify specific devices in passengers in cars. You probably see where this is going.
