Kevin Hart no doubt has power in Hollywood … he got a suspended National Car Rental driver her job back … and then got a pass from cops for making an illegal turn. It all started when driver Genesha Bradley-Douglas stopped her bus at LAX — leaving passengers stranded for less than a minute — so she could take a selfie with Kevin Hart. Apparently National wasn’t happy when they saw our video and sidelined her. He calls it “The Kevin Hart Effect” … an effect that also works on cops.
