Urban legend comes to life?

I could have sworn I'd read this before, either in an urban legend book or a story.

A 54 year old man was driving drunk when he hit and killed a motorcyclist, who was thrown into the car and the driver did not notice until he got home.

A horrible story and a tragedy but it's so familiar. Surely we've encountered it before? And I'm pretty sure I'm not thinking of Creep Show two - "Hey lady, thanks for the ride!"
