Bubba Wallace -- the only black driver at NASCAR's highest level -- is calling for an official ban on confederate flags at race tracks ... saying there's just no place for them in the sport anymore.
"No one should feel uncomfortable when they come to a NASCAR race," Wallace said. "So it starts with confederate flags. Get them out of here."
