This has to be insanely more expensive than metal plates, and in the event of a hit and run the plate won't be left behind to ID the driver. I'm guessing the 20 million they'll save on postage can be put toward the billions it'll cost to outfit every car in California (there are 33 million registered) with a display, mobile network connection (that hardware isn't cheap). So even in fantasy land where these are cheap, lets say $25 a unit it would cost the state $825,000,000. I'd guess the actual price is closer to $100 a unit, so almost 4 BILLION DOLLARS. What a waste of resources. How anyone can think this is a good and cost effective idea blows my mind.
