 Opinion of the Court ," not merely "an inconvenience to be somehow 'weighed' against the claims of police efficiency." Coolidge V. New Hampshire, 403 U. S. 443, 481 (1971). Recent technological advances similar to those discussed here have, in addition, made the process of obtaining a warrant itself more efficient. See McNeely, 569 U.

S., at 15, n. 9.

In light of the availability of the exigent circumstances exception, there is no reason to believe that law enforcement officers will not be able to address some of the more extreme hypotheticals that have been suggested: a suspect
