My teams are using the linked license plate holders which have a finger cutout on the top and bottom (about a 1" half circle). They also have 3D printed double colored license plates that can be flipped based on the alliance.
My question is on the definition of obscured. Is it allowable to have a clearly obscured license plate that you can see about an inch of the top/bottom and a the half moon cutout on the back of the wrong alliance color but can not see any of the text or markings from the incorrect alliance plate. This is attached to the backside of the correct color alliance plate.
Is it allowable to use an official license plate as a vanity plate without a team number on it that does not match the alliance that the robot belongs too.
