For children age two and older, decades of crash data reveal that car seats do not outperform standard seatbelts in preventing fatalities. In a national dataset spanning 30 years, fatality rates for car-seat users and those in lap-and-shoulder seatbelts were nearly identical. The costly and complex car seat industry persists, driven more by emotion and regulation than by solid evidence. Alternative, integrated safety designs could be both simpler and more effective, but public faith in complexity over simplicity remains strong.
