(Hopefully not a long post or too much of a tangent)
I totally get the idea that the corporate side of things has taken some personality out of the sport. Drivers have to conform to corporate expectations, and there are some written rules along with some unwritten ones.
Drivers are probably coached on what they can and cannot say on a routine basis.A lot of corporate money is riding on that young twentysomething, who could potentially wreck a teams sponsorship with just a few words.
In my unrealistic world of ideas, there would be less corporate control. In my heart of hearts, I don't even like multi-car teams. I would ban the teams from being able to communicate with any other competitor during the races (especially with any inter-team coordination).
But with all that said and like it or not, NASCAR has to have corporate support. In addition to this there will still always be a code of conduct. Yes to more freedom of expression and personality, but you still cannot or should not get away with being an (Daniel Dye type of) a-hole, regardless of the corporate influence.
And making it a point to offend a potential audience and sponsors is indeed an act of being an a-hole.
You also do not have to be an a-hole to have some personality.
