In recent crashes and old ones, in big vehicles and small, in one-car crashes and multiple-vehicle crashes, there is no evidence that car seats do a better job than seat belts in saving the lives of children older than 2. (In certain kinds of crashes -- rear-enders, for instance -- car seats actually perform worse.)

robust to a wide range of sensitivity analyses, including limiting the sample to crashes in recent years, particular types of vehicles and crash impacts, and focusing only on safety restraints which are being properly used according to police reports."
