Regarding the gauges located in the center console;
I was able to see, in person, both Concepts, the silver coupe and the orange 'vert, and all
I heard when the subject was asked was that those who saw them liked them, and the vast majority wanted to see them make production.
I do not see them as "gimmicky" or "worthless" at all. It seems everyone is pleased with how the Concept pays homage to the '69 Camaro...
this is one of the details that helps make that happen.
Personally I think they're a nice touch.
