The NFL, MLB, NBA and NHL have all suffered embarrassing labor disagreements in recent years. Not so in NASCAR, because it flattened the two attempts drivers made to unionize. In 1961, Curtis Turner tried to get drivers to affiliate with the Teamsters but NASCAR banned him for life —though that was lifted and he returned in 1965. In 1969, the fledgling Professional Drivers Association boycotted a race at Talladega, which top drivers considered unsafe. When NASCAR held the race anyway, that was essentially the end of any union-like attempt.
