It was the prop dept's responsibility to change from the commercial plate to the prop plate, but this scene slipped by them. It's also interesting to notice that this scene takes place at a real intersection up the block from Universal Studios, which is the direction Squad 51 came from. Note the "Black Tower/MCA Tower" in the background, which houses Universal's executive offices.
