Well, I have a sick fetish with small detail. Which is probably why I even noticed it in the first place. But in any case, your probably right about them just looking over it, but how can you look over the steering wheel and the shifter... They're the closes things to you when your drive.
But yeah, I've checked a retarded amount of pictures. Even screenshots from the creators on the main site, and none of the cars have a reflective shift knob or wheel. Just one more thing to figure out, why? Yet, damn them for dangling something shiny in my face and keeping it just out of my reach. What am I? A friggin' monkey?
