Ghostly car story

This is true story, or so I am told:
~~~~~~~~~~~~
John B., a [location deleted] student, was on the side of the road hitchhiking on a very dark night and in the midst of a big storm.  The night was rolling on and no car went by.  The storm was so strong he could hardly see even a few feet ahead of him.
Eventually he saw a car slowly coming towards him and stopping.
Desperate for shelter and without thinking about it, John got into the car and closed the door, only to realize there was nobody behind the wheel and the engine wasn't on.
The car started moving slowly.  John looked at the road ahead and saw a curve approaching.  Scared, he started to pray, begging for his life. Then, just before the car arrived at the curve, a hand appeared through the window and turned the wheel.  Paralyzed with terror, John watched the hand, but it didn't touch or harm him.

Shortly thereafter John saw the lights of a pub appear a little further down the road, so, gathering strength, he jumped out of the car and ran to it.  Wet and out of breath, he rushed inside and started telling everybody about the horrible experience he had just had.
A silence enveloped the pub when everybody realized he was crying and wasn't drunk.

Suddenly the door opened and two other people walked in from the dark and stormy night.  Like John , they were also soaked and out of breath. Looking round and seeing John sobbing at the bar, one said to the other ....

"Look [name deleted], there's that idiot who got in the car while we were pushing it!!!!"
