Develop a Tasker profile to open maps anytime you drop cell signal so that your location is pulled using GPS.
In my case, this is not what happened. The Life360 History log show something like:
1PM - Home
1:15PM - 12 Miles from Home
1:25: - 20 miles from home
1:35 - Home (Hhhm. travelled 20 miles in 10 minutes)
1:45 - 40 Miles from Home. (240 miles/hour. Engine getting hot. Wife want out)
.

Different Geopresence algorithms work a little differently. I don’t know the details of the life 360, it may default to your home location if you drop cell service.
