I think it’s supposed to make your phone notify you if you move and there is another unknown BLE device constantly moving with you. That means someone put one of those small keyfobs in your backpack. It’d be a known BLE device if you put it there yourself and added it to your account.
There is a threshold. It won’t complain if you’re 30mins on the train. Or driving 2h with a friend. But it will make a noise if something is following you for the better part of the day. I made up the numbers, it’s been a while since I read how those things are supposed to work. And I think they changed things. AirTags will beep at random intervals like a smoke alarm once they lost sight of their paired iPhone. That’s so other people can find them. And Apple can also see if the paired iPhone is traveling along. So they can make a distinction if someone put a tracker in your backpack, or if it’s in their backpack and they’re sitting with you in the car.

So going to work on the commuter train will be A LOT of buzzing on your phone?
Sounds like there’s more to it than that.
