Re: Scary Stuff
I currently work on ANPR and your figures are roughly correct, in daylight. Remarkably, we get closer to 90% accuracy at night using infra-red cams.
Here in Massachusetts (actually, it covers the entire east coast of the USA), we have something called EZ-Pass. It uses a combination of RF transponders and ANPR to bill for tolls. It works up to 70 mph, and there are several examples of this up and running. At night, you can just see the visible bit of the IR flash as it reads the plates. The slow-speed lanes have fixed illumination and the plates, of course, are reflective.
I suspect there is a manual reading of illegible plates going on, and I understand that the plates aren't used unless there's a problem with the transponder signal. Still, quite impressive.
Yes, there's a whole subset of drivers who refuse to use it, because they don't want the guvmint tracking them. They're the ones in the long lines, which, according to our overlords, will soon be gone, as the system is about to displace the toll-takers (overpaid relatives of politicians), with license plate readers used to bill those without tags (at a higher rate, presumably)
