I just had to provide records of my past travel history for immigration purposes and I couldn't find any of my i-94 records. I could sort through emails to find past flight tickets but the data from my Google location tracking history proved to be much more reliable and easy to parse. I was able to get all my flight dates from past 5 years easily with it.

I also like to look for places I've been in the past and Google maps can tell me the dates I've been to a specific place in the past.

So it does provide quite a lot of value at least for me. I completely understand the sentiment that seems to be a majority on hacker news how that's quite a bad idea, how I'm giving away my privacy for convenience and yada yada. But I made the personal decision that Yes it's worth exposing this data to Google and possibly law enforcement that require Google to disclose this information for the convenience I get in return.
