Steven Levitt, of Freakonomics fame, gave a talk at TED in 2005. In it, he put forward the idea that child car seats do not outperform just using a seatbelt to a significant degree for children over two.
In some ways, this is shocking but believable. Take handsfree kits for example. There is no evidence that they are any safer than holding your phone. The dangerous bit is having a phone conversation, regardless of the phone being on handsfree or not. However, because it seems intuitive, because it allows the government to look like they are doing something, and because it allows manufacturers to sell us more stuff, everyone goes along with it.
Could the same thing be happening here?
Well, maybe. It is difficult to argue with the data he presents. However, in the Q&A at the end of the talk, Levitt touches on the issue of whether car seats do provide a reduction in injury and it turns out that they may well do. Other datasets suggest that there is a significant benefit.
Also, the following year the University of Michigan published a study suggesting that there was a significant reduction in risk of death: 28%. The study seems to group front and rear facing seats into the same category, so it would be interesting to see if these groups showed a difference.
Therefore, unless further evidence is published, it makes sense to continue to use child car seats.
