cops have an expectation of privacy on the side of a HIGHWAY...?
Can we have sex on the side of the highway? If not, why?
Do we not also have an expectation of privacy?
Heck, you should visit NC. Our State Highway Patrol officers have sex on the side of the highway all the time, or on some back-roads where they administer “breathalyzer” tests to unsuspecting, but agreeable, female lawbreakers.
