Maybe good in a country that has barily any walking or cycling infrastructure, where every idiot has a gun and where all the biggest serial killers originate from. And where recently your kid can be kidnapped by unmarked unrecognizable fake police and sent to a concentration camp in El Salvador without any legal process.

But when you live in a first world country, your 8 year old should be able to go to school by bike on his own without issues what so ever, would never be kidnapped and would be brought home by a concerned neighbor when he falls and get injured. And would never get lost. You don't need an air tag for that. I've even seen kids go to school on their own in Cambodia without issues. They have over 40 different deadly snakes including 6 types of cobras.

When you treat a kid as an irresponsible criminal and/or idiot, that's what they will become.
