We find particularly troubling Volvo s counterintuitive assumption that an electrical component cannot malfunction and ______ that its unfailing performance can be predicted with absolute certainty in any and all circumstances.

Since the 600-page NHTSA report was on microfilm, Perez proffered only a few transcribed pages, but made clear his willingness to produce the entire report to the district court on request. However, before dismissing the case, the district court instead decided to reserve for trial any question concerning the admissibility of the report on the defect issue. See supra note 4. As the ___ _____ proponent of the report, of course, Perez will need to satisfy the district court on remand that the reports of inadvertent deployments received from consumers by the NHTSA are not inadmissible hearsay. See, e.g., Fed. R. Evid. 803(8)(A) (public ___ ____ agency statements "in any form" setting forth "the activities of the office or agency" are not hearsay). Without regard to whether the entire NHTSA report is admissible, however, there presently appears no reason to believe at the summary judgment stage that the responses Volvo provided in the NHTSA investigation relied upon here could not be introduced as admissions of a party-opponent.
