I grew up in the '80s. It was absolutely unnecessary then, and a pressing need has not since developed. “Be home by dinner” was perfectly serviceable when I’d head off on my bike to see which friends were available to hang out with. Often, I’d be invited to dinner, and the parents would talk so mine knew where I was, usually followed by an invite for a sleepover since it was by then dark.

Abductions of and assaults on kids are statistically far more likely to happen with a known party. This tracking obsession stunts normal childhood experiences, and I’ve not seen any study conclude that kids are overall safer from this level of surveillance.

If uncle Bob is molesting you but your parents trust him, this is all theatre. “At least they’re safe … they’re at Bob’s” my ass. But got forbid you meet of with your friends to build a tree fort outside of an arbitrary radius.
