There is a blind spot on the road, a very sharp curve into a one lane bridge. Well one day the man came racing and skidding around the corner, right into a small school bus. Needless to say, the man and many of the kids were killed. His soul was given the ironic punishment of driving from the house to the bridge forever, the stipulation being that those are his boundaries. The reason being to serve as a constant reminder of his role in the kids' deaths, making what used to be his pleasure spot a tormentfull reminder.
According to legend, his spirit can be summoned by driving to the old house and honking your horn three times. That will make the car appear and chase you, trying to crash into you. The only chance at escape at that point is to beat the skilled ghost driver (who knows every hill, twist and turn of the road) back to the scene of the accident, since the ghost can’t cross the bridge.
