The dissenting Justices criticized the court's decision by suggesting that the original rationale for the "automobile exception" was being ignored. One of the reasons for the "automobile exception" introduced by "Carroll v. United States" was that the mobility of automobiles makes it impractical to obtain a warrant. But in many situations police perform a warrantless search of a car even after the driver has been arrested and the car has been rendered completely immobile. In other situations, the police could choose to detain the car and driver while awaiting a warrant, although the court has recognized that seizing car and driver for the time it takes to issue a warrant may be considered a greater intrusion than performing an immediate warrantless search. Without the reason of mobility, the other reason for the Carroll decision is often the only one in force when a warrantless search is performed: The diminished expectation of privacy in an automobile. The dissenting Justices pointed out that even though an automobile has a lower expectation of privacy, the court has continually recognized that containers do not suffer those same diminished expectations. Furthermore, unlike detaining an entire vehicle and driver, seizing a package inside of the car to await a magistrate is not impractical. Therefore the mobility rationale from the Carroll decision does not apply to containers in the car, which can be removed and therefore do not have the same "practical mobility problem" that a car does.
