It’s safe to assume that Robert F. Kennedy Jr. is unfamiliar with the concept of new car smell.

Carole Radziwill — whose late husband Anthony was best friends with RFK Jr.’s cousin, the late John F. Kennedy Jr. — admitted on the “On with Kara Swisher” podcast that although the politics of the Secretary of Health and Human Services have changed over the years, there’s always been one constant in his life: his love for roadkill.

And thanks to Kennedy’s macabre hobby, riding in his car sounds a lot like a scene from a horror movie called something like, “Minivan of a Thousand Corpses.”

“He had that weird thing about roadkill, always,” Radziwill said on Swisher’s podcast. “He would pick it up from the road all the time and leave it in his minivan, and sometimes he’d forget. There’d be like a skunk under the seat. His minivan always smelled of death.”

The “Real Housewives of New York City” alum added that she knew Kennedy and his late wife, Mary Richardson, “well” and “spent a lot of time” with them before and after her husband died in 1999.
