No it was me who was nitpicking not you 
I agree that in reality these are very small numbers we are talking about. I just wanted to point out that internal decapitation, while a horrible injury and a scary phrase and, yes, a reality, is not the only thing which causes injury in car accidents. If you spend a lot of time on ERF groups then you could be forgiven for thinking there was an absolute epidemic of it happening when this is not really a true representation of the picture.
In reality if you're in a car accident and your child is properly restrained in any seat suitable for their age and size, they will probably be fine.
If you're unlucky enough for the accident to be extremely serious, then it's possible that there is no car seat in the world which could have saved them.
We are talking about a small gap between these two scenarios, larger the younger your child is, and you can absolutely narrow it by using a RF seat. But the chances that you'll be in that scenario in the first place are very small, so the older your child is, the less that it makes sense to prioritise that tiny possibility over things like financial hardship, the safety of other passengers in the car (e.g. an adult who is too close to the dashboard) or even as the child gets older, things like comfort or preference.
If RF is causing no problems then it makes sense to continue, but if it is causing a problem then it can make sense to weigh it against other things.
I agree the "You need to put your child RF otherwise they are definitely going to die" is unhelpful and hyperbolic.
