Parents should be aware. What if child had run under wheels of a passing car
What if's are easy to say, being realistic as a parent, you cannot keep hold of your kids at all times, one parent was in front one behind, I think it is pretty unreasonable to suggest that that the child should be being held directly by one of the parents, there is no indication that child would go on the road. The child was on the pavement where they are allowed to be, the cyclist was on the pavement doing silly speeds where they are not allowed to be. In my humble opinion, the parents are not at fault at all.
