I think there's a difference between an unavoidable accident and negligence. Putting a young child on a motorized vehicle borders on negligent. Putting a young child on a motorized vehicle without proper safety gear is negligent. Perhaps because I couldn't have children,and would have considered a child the most precious gift of all is why I get angry when parents, whose duty it is to protect their child, don't do the basics required to protect their child. God knows you can't lock them in a box for their whole life, but you also don't need to put them into situations that will endanger them. A child riding a bike with all the protective gear on who gets killed by a car is a terrible accident, and not the fault of the parents. A child on a motorized vehicle without any safety gear is negligent on the parents' part. It may not be pretty (the truth seldom is), and the parents will pay the price of guilt for the rest of their lives, and for that reason I feel badly for them. It doesn't change the fact that they were not looking out for the best interests of their child when they put her on the vehicle with no safety gear.
We had a group of teenagers living on the street behind my house whose parents were having domestic difficulties. Maybe in an effort to make up to their boys with material things that which they were not giving them by way of a family life, they bought them motorized scooters, and a go kart. These kids used to ride these things all over the neighborhood. They were about 13 or 14 years old. I live on a corner, and just beyond the corner is the crest of a small hill. These kids used to come fllying out the side street next to my house onto the main road that I live on, and any car cresting that hill would not have seen them in time to stop. You wouldn' t believe the number of times those kids ended up dumped over swerving to get out of the way of a car. And, motorized scooters on a regular road in my town are illegal to boot! I would call the police, not so much because the scooters bothered me(although the noise they made was quite annoying) but because i was sure that one day one of those kids was going to end up lying dead on my front lawn after he got hit by a car cresting the hill just as he was flying out the side street after not looking or stopping for traffic. Finally, after several calls, the scooters disappeared. I don't whether the family moved, or the cops confiscated the scooters, or threatened the parents, or what. I was just glad that they were no longer driving around the neighborhood, because they were a tragedy waiting to happen.
The job of any rescue worker or healthcare worker isn't easy Steve, especially hard when you have to save people from themselves.
