That's still inaccurate as most auto accidents aren't preventable and the governments own data only suggests proper car seats. In fact it is estimated that only 1/3 of deaths related to children in car accidents are preventable ([Source](http://www.thegeorgialawyer.com/third-of-fatal-injuries-suffered-by-children-in-car-accidents-are-preventable/)), so over 2/3s are not preventable.
