not sure that's a parking sensor looks like it's access to something, its more detail to render so I don't think It's been put there for the sake of it. Maybe its a revision like I said or ones a European version and the other is for the American market, different regs etc
The parking sensor I've seen are usually next to the back light.
The only other thing it could be is the tow hook access hole but that is usually behind the registration plate but missing there.
I'm starting to think maybe somebody stuck a texture on upside down somewhere and it's propagated from game to game. In any case it would be cool to find out what that hole is and why it doesn't match any Laferrari I've seen.
