The considerable variation in estimates of restraint effectiveness (from 11% negative to 90% effectiveness) in real-world crashes may be due to the exclusion of non-injury crashes in some studies and to at least some error in reported belt use in all effectiveness studied (higher reported than actual use). A comparison of effectiveness (reported use compared with a 5% lower use) showed a difference of almost 50% in seat belt effectiveness. With seat belt protection lower in frontal crashes, and the number of vehicle occupants not using seat belts, passive protection would result in about 4 to 5 times as much protection against serious injuries as belts. /MSA/
