Abortion is murder and a fit subject for the criminal law. It is also normally not within the family putting it another step outside of any family privacy. It is properly illegal to procure a murder and the purchaser or instigator of such a service is subject to penalties as is the one who provides that service.
Does society in general have a responsibility to ensure parents feed a child? That is within the family.
There is no justification for letting people endanger their children in such a flagrant manner in vehicles.
