> dynamically listed the speed limit in two places, but often it was completely wrong and sometimes it didn't even agree with itself
I had a rental car last year that did this. One speed limit is the (often outdated) speed limit it picks up from the navigation system's maps, and the second in the most recent speed limit sign the cameras OCR'd.
The speed limit from the maps is invariably wrong as soon as you turn off a major road, and the cameras seem to miss about every 3rd speed limit sign...
