I bet I can win this one, if rental trucks count: About 50 meters.
I had a reservation for a rental truck for moving some stuff. At the last minute it turned out we didn't need it. The cancellation fee, if the reservation was cancelled at the last minute, was $50. The rental rate was something like $19.95/day plus something per mile. So I rented the vehicle and drove it around the building to the side where trucks are returned.
