It would be so nice if you politically-correct types would take the time to understand a situation before beginning a tirade against a company or institution. Someone cries racism, and you just jump right in there.
Neither NASCAR nor any other race sanctioning entity "produces" or "develops" drivers. Drivers do not work for NASCAR. You might like it better if the team owners chose their drivers by race or sex, rather than by driving skills. But the entire racing industry would fail if that were the case. When are you going to go after NBA, NFL, and MLB about their lack of whites, or females?
Of course, this would make no sense, since the players are hired by the team owners, and they are looking for players that can help them win, without regard to sex or race.
Please, use some common sense in the future. You're not using any now.
