Details on how such plates would work aren't entirely clear, but supporters say that ads would potentially be displayed only after a car is stopped for four seconds at a red light, or when in traffic. Additionally, the car's plate number would be visible at all times. Call me crazy, but no matter how hard the plate designers try to prevent distracting drivers, anything that flashes in front of me when the car is stopped will catch my eye. Maybe that's the point? Plus, if this is akin to driving around with a mini computer screen on your bumper, I could see them being a target for thieves, not just my eyes. What do you think?
