I agree with your comment but disagree with the framing that these are necessary because parents “fail”. The safety mechanisms you point to are not a result of parents failing, it’s a result of a common agreement that society as a whole benefits from certain guardrails. Seatbelts were very controversial! But after you realize that a seatbelt is a small inconvenience that can prevent you or your children from being violently ejected from the vehicle and splatting on the pavement in the event of a car crash, we agreed as a society that the public health good outweighed the slight inconvenience of wearing a seatbelt. Nothing to do with the failings of parents. Parents already feel like failures most of the time already as it is.
