I'm wondering what insurance companies are going to say. I have a feeling they will be the driving force at least in the US, since they are the ones picking up the bills.
Will that same law apply when the kid is operating a motorized vehicle? Especially if they're operating that vehicle illegally?
TBF, it hasn't been a problem so hey, maybe these kids have a lot more sense than we give them credit for? Maybe I should just be grateful that those girls were outside playing instead of being in a screen and were feeling a little "dangerous" and rode 3 up on an e-bike?
