Is the plate the hard part? What if we throw a stunt at it?EDIT: To clarify, the difficulty Amu has with hiding the number plate is basically that she has to keep doing so, consistently, while unable to see it.
[X] Take pictures of the front and back plates with your phone camera and use the pictures as focus aids.
If the color is hard too, it may be better to just not bother - if our focus drops, our car suddenly changing color would be very noticeable.
