You can't legislate intelligence. Even with laws and parental supervision you can't guarantee the safety of children. You can't stop adults from driving while texting or running over their own children in car ports either. Although a small percentage of people end up injured or dead because of these and other activities we see and sometimes feel the effects. Some of us occasionally have opportunities to attempt education or change. Others make fun of things. I heard something about an enforced ebike training or class for children in California recently.
