What is the test for reasonable suspicion in a motor vehicle case?

We recognize that, in some circumstances, wholly innocent acts, when taken together, may give rise to reasonable suspicion. See United States v. Sokolow, 490 U.S. 1, 9 (1989) ("Any one of these factors is not by itself proof of any illegal conduct and is quite consistent with innocent travel. But we think taken together they amount to reasonable suspicion."). In this case, however, the wholly innocent acts, when viewed cumulatively, give no more rise to reasonable suspicion than they do individually. Moreover, some of these "factors" may not be considered under any circumstance: for example, the fact that the vehicle was not exceeding the speed limit. In light of the above, a reasonable jury could readily have concluded that the officers' decision to stop the plaintiffs' vehicle did not meet the standard of reasonable suspicion.
