It doesn't meet your needs, but I have something kind of like this for my iPhone.

I wrote a Shortcuts Automation that triggers when CarPlay disconnects. It then grabs the current date and time, the current latitude and longitude, the street address and an Apple Maps link and appends it to a "Location Log" note in the Notes app. I could've dumped it to a file instead, but I wanted it in a note.

It requires zero interaction from me.

That's a very clever trigger and will reduce a lot of redundant data. But I'm in favor of public transport and bicycles. Maybe I should look into other possibly interesting events e.g. network changes. Thanks for the advise!
