Child safety seats

More info on child safety seats:

One of the items for evaluation was child safety seats. We evaluated child seat performance based on the child seats implicit to usage in that era and found that car seat belts were more effective for children and infants. NHTSA was incensed by this conclusion and we had to reanalyze the data numerous times and ways eliminating parts of the data they decided they did not like for, in our opinion, questionable reasons. No matter how the data was sliced and diced we found that car seat belts were more effective for children and infants (highly statistically significant effects).

There are some other reasons for liking child car seats. Car manufacturers like them because parents buy bigger and more expensive cars. A lot of parents bought SUVs just to easily accommodate child car seats. Also, a lot of moms like the child car seats because they keep the child more confined, and less likely to annoy the mom. The safety benefits are minimal, at best.
