Those roof top carriers are mostly used for transporting lightweight
bulky items, like bedding, winter garments, breakables like glassware,
and such. People typically use those carriers when moving and don't
trust the movers with Aunt Jane's lamps, or bulky musical instruments,
like a cello. Such bulky items are not permitted to block vision on
Interstates so they can't be placed into the passenger compartment.
