What is it?
California is considering electronic license plates which would look normal when the car is moving, but when stopped at a red light, would flash advertisements to the motorist behind them (rear plate only).
Why do it?
California lawmakers are considering this to open a new revenue stream for the State, claiming it would help alleviate the existing $19 billion dollar deficit.
What's the down side?
How long before kids hack into this and show porn, play video's, or use it to promote their own things or, to turn the license plate dark to avoid police, or change the plate # for criminal activity? What is the potential to distract the driver while slowing behind a stopped car for more accidents?
