Parking Meter
The meters seem to serve no purpose at all. You can activate them once to start the timer but the timer doesn't seem to end afterward. They were made in the old days before the "nukes" hit. They're is no factory or production facility in the Capital Wasteland, Point Lookout, or The Pitt. They are indestructible and will always work. They also cannot be used as a weapon. You cannot store items in them nor store in inventory.
