I would like a tag that just records its own GPS coordinates locally on-device, every so often, and then when my dog comes home, I can check where she's been.
Does this exist?
I have used them before on various bikes and they work just fine. Battery life is about 25 hours, it is weather resistant, and then you can sync them after you record an activity. And at less than $30, if it gets lost, it isn't the worst thing in the world.
Yes. As part of a major effort to reduce the abuse potential of AirTags, something that people have been very justifiably demanding.
Perhaps some people in a uniform could get access to that computer, physically or otherwise, and then have access to lots of interesting location histories from it, and they may not have your best interests in mind.
