I'm not sure I see the problem. From NASCAR, World of Outlaws, down to the local level, these guys race together week in and week out, pit next to each other. They go out drinking together, eat together. I think the problem you are preceiving is due to the never ending glut of coverage compared to the "old days." It used to be that you wouldn't see it just because they didn't show it. You left one week when a couple drivers had issues with each other and basically assumed it carried over forever, because you just didn't see it every single day of the week.
