A woman chased down actor Gary Busey after he allegedly hit her car on a Malibu highway and drove off — and then refused to hand over his insurance information when she caught up to him at a restaurant.The 79-year-old “Buddy Holly Story” star is under investigation for his involvement in the alleged hit and run that happened Wednesday, the Los Angeles County Sheriff’s Office confirmed to The Post.The woman, who was not identified, told TMZ she was driving down the Pacific Coast Highway when Busey pulled out of a shopping center and struck her back bumper before leaving the scene.“Sir, you hit my car, I need your information,” the woman shouted to the “Point Break” star as they drove alongside each other, according to wild footage obtained by TMZ.“Sir, you hit my car,” the woman screamed louder as Busey zoomed away.Eventually, she caught up with the actor in a restaurant parking lot and demanded he hand over his insurance information as she pointed out scuff marks on his Volvo, according to the footage.“I want the information,” she said sternly. “I’m private,” Busey replied as he got back into his car.“It doesn’t matter, you hit me,” the woman shot back.
