Yup, this is how some of the products used to work. I worked for Lockheed/Martin, who managed the TCA (Transportation Corridor Agency), a series of toll roads in the Orange County, CA area. To catch violators (non paying drivers), we used radar tripped cameras in conjunction with custom image enhancement software developed for the purpose. Pictures were taken and toll violation tickets sent to the driver via their DMV info. I asked some questions about how people tried to avoid tickets and they described a product like the one you're talking about. Interestingly enough, if you went fast enough at that time, you could be out of the frame by the time the camera snapped the pic. Speed had to be 115+ though. People would also take their plates off and do stuff like cover the plates with mud or tape pieces of paper over them.
