Correct. > Levitt, et al, used only FARS data, which only records fatal accidents. A hypothetical accident where only the child would have died but that was prevented by the restraints would therefore not show up in the data, leading to the value of the restraints being under reported. This is the same regarding any type of restraints, including seat belts, no? Also, you should realized that all of their extrapolated data is also hypothetical, and relies on spotty reporting from police. Please note, that I am not convinced that Levitt has it right, just that he is not incorrect regarding the data.
