Let's leave traffic enforcement to the cameras, much safer for the police, who can then spend much more effort going after license plate violations with gusto (and I'm serious about this). Just train the cameras to recognize cars with unrecognizable license plates, then transmit the data to the police in real time.
Ya, right now its just an add on violation if they do pull you over, or they use it as a (very valid) excuse if they want to pull you over for something else.
