My wife and I got into an argument about this when it was time to switch our kids car seat so I pulled up their recommendations and read their sources. Their cited evidence doesn't support their recommendation at all (nor did it when they first made the rec in 2011).

Their 2011 rear facing recommendation is based on a retracted article and their 2016 rec is based on the same article's data except using a smaller dataset which they acknowledge is not statistically significant. The only other data cited looks at rear facing Swedish children compared to _unbelted_ Swedish children.

I went back and reread it to make sure I was remembering right. I'm dumbfounded that this was allowed not only to stand as a rec, but was increased (deepened? made stronger?) when they had even less data than they did before. I get that it feels like it should be safer, but that's not science and I would have expected a group making medical and safety recs to maintain a higher standard.
