I live in the SE US suburbs and a regular story on the news are fears over roaming packs of kids on e-bikes or e-motorcycles. Now, while the safety concerns of reckless riding are warranted, it also tells me that at least some of the kids are alright.
I live in a low density, large neighborhood where kids 8-17 are out roaming all the time, the older half heading to adjacent shops and other neighborhoods. I recognize and know who most are and their parents. The common trend I see is a purposeful limiting of screen time.
We have the same "problem" where I live in central coast CA. It's so rad to see kids ripping e-bikes all over town. Would I prefer the kid riding on the back seat isn't staring at her phone? Of course! But at least they are outside exploring! Fwiw most of the kids I see with this freedom are Mexican but that could be because I live closer to and work downtown, closer to lower income areas and not in the suburbs.
