It's only for riding..and really it's only for her to find me when I get into some mechanical or scary weather and need her to pick me up. It's happend a few times in the past so in that sense it is a good idea. She also has crazy anxiety about me riding on public roads; so really, it's to help her alleviate that.
Then use Find My Friends. Once you initially set it up on both phones, you never have to touch it again. It's the easiest and more fail safe.
