Also, what about logos and brands of shirts and hats? Do they prohibit certain brands or logos?
Not a racer, but I wanna comment on this.
This season, the Chippendales wear shirts that say that they're affiliated with the company (not sure if those are shirts you can get from their store, if they have one).
Trey/Lexi are wearing Longhorns apparel, and production doesn't blur out the almighty longhorn emblem.
The Beekman boys sport shirts that say the name of their farm/company.
So I would say if the racers are directly affiliated with the logo/brand, then TPTB doesn't blur those things out?
Same could be said with the globetrotters in Season 15/18.
