California DMV has already had some dialog with us, (PIA, California's Prison Industry Authority) about putting RFD tags into every license plate, so they can charge fees by-the-mile!
They want to track every vehicle that drives in California and charge hwy fees per mile driven! I suppose this technology would provide plenty of other useful information to DMV/CHP as well!
The world is getting smaller!

P.S. Caltrans has been looking at putting photo camera's on freeway overpasses and writting speeding tickets 24/7. They could also track any license plate number as it crossed the state.
Also, the police here have license plate readers that can scan & check hundreds of plates per hour as they drive past. The damn meter-readers use it here for writting parking tickets, they just drive by and scan your plate.
