> The authors allegedly use boosters and car seats for their own kids, even after writing that chapter - let that sink in for a while... Because it's the law and you run afoul of child endangerment laws if you don't. After watching Levitt's TED talk and reading the remarks from Durbin and Winston, I tried to find some published research about the matter and didn't have much luck. Levitt was very specific about what they looked at and how the conduced their research. Their conclusion was that it warranted further research. Durbin and Winston's comments were very general and came off as very "trust us". I'm wondering if anyone else might have a link to one of their actual studies? I like the suggest Levitt made of automakers integrating 5 point child harnesses into backseats. This seems like such an obvious improvement that could be an upgrade option when purchasing a new vehicle.
