Yes, but every time I’ve shown someone their location map they have not remembered turning it on.

I think this is in part to google prompting you pretty much every time you use maps or other web tools to turn on location history for improved functionality. I think lots of people don’t understand that and just turn it on to remove the prompt.

Kind of frustrating as this could be done in a privacy preserving manner by keeping all location data local on device and overlaying it on the map locally. Functionality wise, google doesn’t need these data.
