Requirements:
(1) Stop cars on some neutral, articulable standard (i.e. every car)
(2) Be designed to serve purposes closely related to a particular problem pertaining to automobiles and their mobility (drunk driving - okay due to pervasiveness of drunk driving problem; drugs - not okay because the purpose of such a checkpoint is only to detect evidence of ordinary criminal wrongdoing)
