I have much less of a problem with instant lookups against "hot lists" for expired plates, or wanted individuals (though no guarantee that the driver of a car at any particular time is that person, however) than I do with them keeping the data.
I don't see any good reason that they should be allowed to store the data for later analysis, especially if the "hot list" check comes up empty.
The fact that I'm spotted in public is not an unreasonable invasion of my privacy. Nor is a check of my license plate; this has already been possible, if less efficient, ever since patrol cars had radios.
Keeping a log forever of everywhere I've been spotted is unreasonable, if I'm not otherwise under active investigation.
