Look since none of us are Tony we will never know who or what he meant and if it was planned or just out of having finished a race and being happy just said what was on his mind.
Personally I think he may have been thinking things as he was heading to victory lane and then being that he is Tony just said what was on his mind. Look JZ was a user and he finally figured that out and from some things I have heard she was still showing up after they broke up and maybe he was sending a message.
Tony has been who is from the beginning you either love him or think he's an ####. I happen to love him because he does not try to be what others want just to be more marketable(Jimmie, Carl, and others).
