This was called 'Stuck' when it was an original movie idea...
Check out the movie "Stuck" (2007). It was based in the same concept. "Stuck" recreates what was an actual event that occured several years ago. A young home-care worker hit a homeless man late one night. She actually drove home with him stuck in her windshield. She then proceeded to leave him in the garage, dying, while she figured out what to do. I won't tell you how it ended up, but it was definitely based on a very true event.
Experience the awe and mystery which reaches from the inner mind to...The Outer Limits
