Would it be acceptable to put chometzdik items in the trunk of one's car, and then sell the contents of the trunk to a non-Jew before Pesach? Assume one would not open the trunk during Pesach, but would indeed drive the car.
My motivation for asking is that it seems like one would need permission to transport objects that belong to someone else, so I'd wonder if there is a special stipulation that sold items need to remain in one place during Pesach.
