Not sure I understand how an RFID system would do anything to stop private companies from using ALPR. If anything it would be easier and more accurate for them and they could pick up far more plates per second since they wouldn't be limited to scanning just what is in the field of view of the camera. RFID would also let them read plates that previously were "invisible" to the computer vision systems such as plates with a cover on them, dirty or snow covered plates. I imagine it would only be a matter of time before private entities built a system to read the plates given the wide distribution of the spec that would be needed for police scanners to be built.

A telephoto lens can read a license plate from a great distance while alerting no one. In the normal case, one would have to be in close proximity to read a car's RFID tag.

- fnordfnordfnord 12y agoYou can detect a car any number of ways. Detect a car without also getting an RFID and you can generate a report for a nearby traffic police to follow up on. We already use RFID for access in a number of places, such as tool booths. An RFID-less car would get noticed there, and I don't see any reason that police vehicles wouldn't be equipped with the transponders, so I think in some cases it might be harder than it currently is.
