Based on that video, I should just drive close enough to the car in front of me that half or less of my license plate is readable by the camera. Thanks for increasing road safety, automated ticket systems.
Although it would be resource intensive I think they still need to do driving tests that realistically assess driving skill and assign speed limits accordingly. That's the only way I would accept the new personal electronic vehicle speed monitoring systems that are starting to hit public use. Theoretically you could automate the testing by putting people in a simulator, and letting it judge their safe reaction speed.
I would appreciate having a higher ranked license than the person with the handicapped plates driving 10 mph under the speed limit in the left lane with their right turn signal on perpetually. (I only mention handicapped plates because with only one exception every single person with them I've seen has been a terrible driver in one way or another.)
