Buried in sand with only head above ground

Are you sure you are not thinking from one of the stories from the movie Creepshow?
A guy (Ted Danson) gets buried with in sand with only his head sticking out while being filmed. No car running over him though...

The episode was called Best Shot and the story was about a Cocky and obnoxious defense attorney named Steve and his passive law professor buddy Brett decide to let it all hang out and gleefully indulge in irresponsible behavior while embarking on a cross country joyride. The duo film their exploits on a portable video camera. After Steve accidentally runs down a man on the side of the road, he does his best to hide what he's done from Brett. However, the dire consequences of Steve's grave actions eventually catch up with him when the pair stop off at a remote redneck bar in the middle of nowhere.
