The plate would display standard plate information when the car is moving, but would also display ads when the car is stopped for more than 4 seconds (say, at a red light). Not distracting or annoying at all! 'The bill has received no formal opposition. It passed unanimously through the Senate last month and is scheduled to be heard Monday by the Assembly Transportation Committee.'"
