A controversial new NASCAR rule designed for “world-class drivers” could give Helio Castroneves an automatic berth into the Daytona 500, and, should the four-time Indianapolis 500 winner use the provisional, it would make for the largest field in a decade. It’s a complicated rule that was written into the charter agreement that 13 teams signed last September and is similar to a “promoters provisional” in that it gives NASCAR the ability to designate one driver as a guaranteed 41st entry. Three-time Daytona 500 Denny Hamlin said the rule “reeks of desperation” by NASCAR, calling it nothing but a gimmick to attract big stars to stock car racing.
