I'm trying to figure out what the problem actually is here. Is it that kids have access to a motor vehicle that can go fast enough to hurt them? Is that the primary issue under discussion? Might be good to treat them how some northern states treat snowmobiles and require a safety certificate that kids can get by doing a drivers ed-type class. Cops don't have to putz around harassing kids for enforcement, just require it be presented to purchase, to get school parking, submitted after a crash, etc. But that should be a state solution, not a municipal one. Schools should be educating kids about safe use, and cities/towns should consider providing safer infrastructure for micromobility. I think the best you can and should be doing is making it as safe as possible, not prohibiting. Real adaptation will require some investment at the state level just like any other class of vehicle. But municipal representatives can encourage acceleration of that process.
